History of the Institute. During the period of its activity, the Institute has made a significant contribution to the development of mathematical science, the training of highly qualified personnel for the republic and has become one of the recognized centers of mathematical research at the international level. The path taken by the Institute of Mathematics’ personnel is vividly expresses in the development of mathematical science in Uzbekistan.
Initially, the Institute was created as part of the Academy of Sciences of Uzbekistan as the Institute of Mathematics and Mechanics with a computer center. In addition to mathematics, scientific research was also conducted in mechanics, theoretical geophysics, seismology, and computer technology. Over time, the directions of mechanics and seismic resistance of structures, cybernetics, and seismology separated as independent institutes.
Academicians T.N. Kary-Niyazov and T.A. Sarymsakov, the first presidents of the Academy of Sciences of Uzbekistan
In various periods, the Institute of Mathematics was led by prof. N.N. Nazarov (1943-1947), prof. V.A.Dzhoggio (1947-1950), Acad. V.I. Romanovskiy (1950-1952), Acad. V.A. Bugaev (1952-1957), Acad. S.Kh.Sirazhdinov (1957-1960 and 1962-1967), corresponding member V.I. Gubin (1960-1962), Acad. M.S.Salakhitdinov (1967-1985), Acad. T.D.Jurayev (1985-1992 and 1997-2003), prof. B.B.Rikhsiev (2003-2004) and Acad. Sh.A. Ayupov (1992-1997 and from 2004 to the present).
In 1954, the institute was named after V.I. Romanovskiy, the founder of the mathematical scientific school of Tashkent. The most significant achievements of the Institute can be listed by creation of scientific schools recognized by the world mathematical community on functional analysis, differential equations, probability theory and algebra thanks to the efforts of V.I. Romanovskiy, T.A. Sarymsakov, S.Kh. Sirazhdinov, M.S. Salakhitdinov, T.D. Juraev. Currently, these schools are run by academicians Sh.A. Ayupov, A. Azamov, Sh.A. Alimov, Sh.K. Farmonov, and J. Hadzhiev.
The scientists of the Institute also carried out fruitful research and made an enormous contribution to the study of the history of the development of mathematics in the Middle Ages (academicians S.Kh.Sirazhdinov, G.P. Matvievskaya and others).
Scientific research of the Institute employees was awarded five State Prizes of Uzbekistan. In 2017, the State Prize of the first degree in the field of science and technology of the Republic of Uzbekistan was awarded to a team of mathematicians - academician Sh.A. Ayupov and his students, doctors of sciences K. Kudaiberganov (KKSU), B .Omirov (NUUz) and U. Rozikov (IM AS RUz) for the fundamental research “Development of the theory of non-associative algebras, derivations, and nonlinear dynamical systems”.
In 2019, PhD student of the Institute, J. A. Karimov, was awarded the State Scholarship of the President of the Republic, and PhD student S. Shopulatov became the laureate of the “Mard O’g’lon” State Prize.
Academician Sh.A. Ayupov and prof. U.A. Rozikov was elected as Fellows of the World Academy of Sciences (TWAS).
The Institute has a scientific council for awarding PhD and Doctor of Science degrees. Over the past five years, 12 doctors of philosophy (PhD) and 13 doctors of sciences have been trained.
The most important scientific research results:
In the field of algebra and functional analysis.
Based on the theory of operator algebras and non-commutative integration, a new algebraic approach to the description of the space of observable of physical systems in statistical mechanics and quantum field theory is proposed.
The structural theory of finite-dimensional Leibniz algebras and their complete classification for small dimensions are constructed.
The theory of p-adic systems in statistical mechanics and nonlinear dynamical systems in population biology is developed.
Topical issues of ordered and non-associative algebras have been developed as applied to problems of non commutative integration, quantum theory and others, which have received worldwide recognition.
Scientific discussions of Sh.A.Ayupov with Fields medalist Professor E. Zelmanov (USA) and Professor of Sichuan University (China) F. Eshmatov at the Institute of Mathematics.
In the field of differential equations and dynamical systems.
Methods have been developed for solving basic boundary value problems for a third-order equation in multidimensional infinite domains. Exact conditions for the summability of multiple series and Fourier integrals associated with arbitrary elliptic operators of piecewise smooth functions are found.
The boundary value problems for parabolic-hyperbolic equations with fractional differentiation operators are studied.
A new one-step method for the approximate solution of the Cauchy problem for quadratic dynamical systems is developed. An algorithm for the numerical integration of a high degree of accuracy based on the Taylor formula is proposed and an explicit estimate of the remainder term is found. The connection between the Taylor formula and the generator of N. Chomsky grammar is established. The fractal structure of the terms of the Taylor formula is revealed.
Computer programs have been developed with the aim of automating research work on dynamical systems, allowing to build phase portraits of two-dimensional and three-dimensional dynamical systems through interactive control of the image of a phase portrait.
In probability theory and mathematical statistics.
New methods have been developed for stochastic and statistical analysis of random processes, including models describing real phenomena. Integral-local versions of the central limit theorem for sums of independent random variables in the series scheme are proved. The asymptotic properties of branching processes with immigration and the limiting distributions for the total number of particles participating in such processes are studied. A new method for obtaining bootstrap versions of U-statistics from dependent observations has been created.
In the field of computational mathematics.
A theory is developed for constructing optimal cubature and interpolation formulas in Hilbert spaces, and optimal cubature and quadrature formulas are obtained for the approximate integration of strongly oscillating and singular integrals. Invariant cubature formulas with a minimum number of nodes on multidimensional spheres are constructed.
Academician A. Azamov and his students developed a new mathematical model of the heat transfer process in rotating regenerative air heaters (RVAH) of heat power stations. Based on the model, a computer program was created that controls the operation of the RVAH.
Professor F.T. Adylova, together with her students, conducted research on new methods for assessing the model's ability to sample when constructing a structure-activity model in drug development. They got new predictive activity models for a number of alkaloids.
A software tool for monitoring and forecasting the state of the atmosphere in industrial regions developed by scientists from the department of “Mathematical Modeling of Nonlinear Systems” was introduced in the activities of the Samarkand Regional Department of Agriculture and Water Management. As a result of implementation, the economic effect amounted to 72.3 million soums per year.
An experiment was conducted to study the distribution of dust and salt from the drained part of the southern Aral Sea region in the surface and boundary layers of the atmosphere.
Based on the results obtained over the past 5 years, scientists of the Institute have prepared and published 9 monographs on modern problems of the mathematical sciences, including 6 in foreign publishing houses and 11 proceedings of scientific conferences held by the Institute have been published.
