Past Achievements and Future Research

 

Summary of completed research and its scientific and technological impact

 

Research Conducted During the Past 15 years

A collection of methods for construction of slow invariant manifolds has been developed, in particular the analogue of Kolmogorov-Arnold-Moser methods for dissipative systems. The nonperturbative deviation of physically consistent hydrodynamics from the Boltzmann equation and from reversible dynamics, for Knudsen numbers  near one, was obtained.

 

The theory of simultaneously dissipative operators and tools for global stability analysis were developed. An explicitly solvable mathematical model for estimating the maximum efficiency of turbines in a free (non-ducted) fluid was obtained. This result can be used for hydropower turbines where construction of dams is impossible or undesirable.

 

A family of fast training algorithms for neural networks and generalized technology of extraction of explicit knowledge from data was developed. These algorithms are now in use in medical expert systems and in anti-terrorism security systems in Russia (the system "Voron").

 

The geometric seven-cluster structure of the genome was discovered.

 

Summary of current research project

 

The Geometry of Irreversibility. A new general geometrical framework of nonequilibrium thermo-dynamics will be developed. Our approach is based on constructive methods of invariant manifolds elaborated during the past two decades. The new methods allow us to solve the problem of macro-kinetics even when there are no autonomous equations of macro-kinetics. These methods will be elaborated together with computational algorithms. Each step of these algorithms should be physically consistent. The notion of the invariant film of non-equilibrium states, and the method of its approximate construction transform the problem of nonequilibrium kinetics into a series of problems of equilibrium statistical physics. The main specific problem for application of developed methods will be the problem of dynamic memory appearance in macromolecular complexes. Such memory effects may be important for chromatin dynamics and its role in functional nuclear organization. Spatio-temporal organization of chromatin will be studied.

 

Results and Projects (1971-2004)

 

1. The beginning (1971-1975)

Two scientific contacts determined my scientific work during 1971-1975: Prof. V.P. Mikheev (technical sciences) and Prof. V.B. Melamed (functional analysis). With Prof. Mikheev we created models of contact net and contact devices and developed new stations for technical diagnosis. Perhaps the main results of our collaboration are: stations for technical diagnosis that were in use on the USSR railways, new methods for modeling of  the dynamics of contact net and contact devices, and applied software for implementation of these methods.

 

Prof. Melamed was from the Voronezh mathematical school. We introduced the notion of a Fredholm analytic subset of Banach space as a subset that admits a local representation by a set of zeros of an analytic mapping whose differential is Fredholm. The maximum modulus principle and an analogue of the Remmert-Stein theorem were proved.

 

2. Chemical kinetics and topological dynamics (1975-1980)

Global constraints for the dynamics of systems follow from the well-known local thermodynamic constraints.  If a chemical system is one-dimensional (the number of different substances is equal to the number of independent balances plus one), then the equilibrium encircling is impossible. Such systems move monotonically to their equilibrium states, if external conditions are equilibrium.  If the dimension of the system is greater than one, then this monotonicity may be broken.  The effects of “equilibrium encircling” appear. The exact thermodynamic boundaries for the maximal amplitudes of these effects were found. The search for boundaries of the equilibrium encircling is based on the analysis of Lyapunov function trees in the balance polyhedra. The constructive theory of trees of convex functions in convex polyhedra was developed. These results were summarized in the book Equilibrium Encircling: Equations of Chemical Kinetics and their Thermodynamic Analysis (Novosibirsk, Nauka Publ., 1984).

 

A systematic analysis of singularities of transition processes in general dynamical systems was also undertaken.  Dynamical systems depending on parameter were studied and a system of relaxation times was constructed. Each relaxation time depends on three variables: initial conditions, parameters of the system and accuracy e of relaxation. The singularities of the relaxation times as functions of initial data and parameters under fixed e were studied, leading to a classification of different bifurcations (explosions). The relationship between the singularities of relaxation times and bifurcations of limit sets was investigated. The peculiarities of transition processes under perturbations were studied. It was shown that perturbations simplify the situation: the interrelations between the singularities of relaxation times and other peculiarities of dynamics for general dynamical system under small perturbations are the same as for smooth two-dimensional structurally stable systems. These results were summarized in my PhD thesis (1980).

 

3. Biological kinetics and functional analysis (1980-1990)

Does the dynamics of distributed systems which models biological evolution always lead to a discrete distribution? (In the biological context this question can be reformulated as follows: is natural selection really effective if the initial diversity is sufficiently rich?)  In order to answer this question, a theory of special dynamical systems in the space of Radon measures on compact space was developed.  These are systems with a specific conservation law: the conservation of support of measures. There are characterization theorems for omega-limit points, and different theorems about efficiency of natural selection. The qualitative picture of these results was summarized in the book: Demon of Darwin. The Idea of Optimality and Natural Selection, A.N. Gorban, R.G. Khlebopros (Nauka Pub. Moscow, 1988, 208 pp). A short review of these results was given in the talk “Optimality, adaptation and natural selection - the mathematical way to separate sense from nonsense”, available on-line at http://mystic.math.neu.edu/gorban/evolution.pdf .

 

This abstract theory has found very practical application. My former PhD student, E. V. Smirnova (now Professor Smirnova) discovered that the approximate dimension of the cloud of physiological data of a group precisely characterizes the level of adaptation of this group to the living conditions: when the group members exhaust their adaptation resource then the dimension usually decreases.  It decreases usually, but not always.  Sometimes the dimension goes another way. We explained the effect, and, on the other hand, predicted the exclusions. The results were confirmed by thousands of experiments with different populations and groups: from human to plants and fungi. Now the developed concept of correlation adaptometry is in use for monitoring needs in Siberia and Far North.

 

4. Neural networks (1985-now)

In 1985 I stated the problem of effective parallelism as a main problem for our group for the next decade. In 1986 V. Okhonin (former PhD student) published a new algorithm for training neural networks (for synchronized and non-synchronized networks, for discrete and continuous time, for systems with delays in time, and for many other cases).  The central idea was the flexible use of duality (it is a rather usual step in optimization methods). (At the same time, Rumelhart D.E., Hinton G.E., Williams R.J. published a particular case of this algorithm that became famous under the name “back propagation of errors”.) For several years we tried to make the training algorithms faster, and network skills more stable. During an interval of fifteen years (1987-2002) we developed a generalized technology of extraction of explicit knowledge from data.  This technology was implemented in a series of software libraries and allowed us to create dozens of knowledge-based expert systems in medical and technical diagnosis, ecology and other fields.

 

On the base of this approach, the Russian Close Corporation "Applied Radiophysics - Security Systems" developed neural network-based security systems (1997 – 2003). This Russian system "Voron" was the laureate of the international exhibition "Frontier-2000" (see http://etic-m.narod.ru/company.htm, http://www.grand-prix.ru/catalogue/perimeter/voron/solution/ (in Russian).

 

The results were summarized in several monographs, 16 PhD theses were submitted, and 3 scientists prepared Doctor of Science degrees. The developed software is in widespread use in the former USSR, and our lab in Krasnoyarsk now serves as the Russian National Center for Neuroinformatics and Neurocomputing.

 

5. Physical Kinetics and Invariant Manifolds (1977-present)

The concept of the slow invariant manifold is recognized as the central idea underpinning a transition from micro to macro and model reduction in kinetic theories. We developed constructive methods of invariant manifolds for model reduction in physical and chemical kinetics. The physical problem of a reduced description is studied in the most general form as a problem of constructing the slow invariant manifold. A collection of methods to derive analytically and to compute numerically the slow invariant manifold is elaborated. Among them, iteration methods based on incomplete linearization, relaxation methods and the method of invariant grids have been developed. The systematic use of thermodynamic structures and of the quasi-chemical representation allows us to construct approximations which are consistent with physical restrictions at each step.

 

There are many examples of applications: nonperturbative derivation of physically consistent hydrodynamics from the Boltzmann equation and from reversible dynamics, for Knudsen numbers Kn near one; construction of the moment equations for nonequilibrium media and their dynamical correction in order to gain more accuracy in the description of highly nonequilibrium flows; the kinetic theory of phonons; model reduction in chemical kinetics; derivation and numerical implementation of constitutive equations for polymeric fluids. A review of this direction of work is now published in Physics Reports, and is available on-line: http://arXiv.org/abs/cond-mat/0311017

 

6. Bioinformatics and Geometry of Genome (1990-now)

Is it possible to study the genetic text on the same way as A. Kolmogorov studied poetry? Is there a footprint of biological sense in statistical features of the genome? This question needs to be carefully solved. The result may be positive or negative.  Nevertheless, we should study this problem.  We have investigated a numbe of questions in this direction.

 

Some positive results have been obtained and published during the past fourteen years. In particular, the clear seven-cluster structure of genome was identified. We studied cluster structure of several genomes in the space of olygomer frequencies. The result: many complete genomic sequences were analyzed, using visualization of tables of triplet counts in a sliding window. The distribution of 64-dimensional vectors of triplet frequencies displays a well-detectable cluster structure. The structure was found to consist of seven clusters, corresponding to protein-coding information in three possible phases in one of the two complementary strands and in the non-coding regions. Awareness of the existence of this structure allows development of methods for the segmentation of sequences into regions with the same coding phase and non-coding regions. This method may be completely unsupervised.
