Mersaid Aripov (20 September 1939) is an Uzbek mathematician, informaticist, and theoretical astrophysicist author of several scientific monographs in the field of blow-up solution theory.
Aripov was born in Tashkent into a family of teachers.
In 1961, at the age of 22 he graduated from Tashkent State University, majoring in Mathematics. In 1963–1968, he worked as a researcher and graduate student at the Computing Center of the Russian Academy of Sciences. In 1995, Aripov received a Doctor of Science in Physics and Mathematics.
In 2016–2019, he was head of the department.[1] ofaApplied mathematics and computer analysis at the National University of Uzbekistan.[2] From 2019 to the present, he has been a professor at the Department of Applied Mathematics and Computer Analysis of the National University of Uzbekistan.
Occupational activities[edit]
Mersaid Aripov started work at the National University of Uzbekistan in 1961 as a senior laboratory assistant. After 63 years of fruitful work, he went from a senior laboratory assistant, researcher, senior lecturer, associate professor, head of the department, and chairman of the trade union committee to the first vice-rector of the university.
Aripov successfully combines educational and methodological work[3]with scientific work[4] in the fields of applied mathematics and information technology, Artificial intelligence, Computational linguistics, NLP, and Information security[5]
Contributions[edit]
Aripov was one of the first in the world to create the asymptotic theory of solutions of second- and third-order generalized Emden-Fowler equations,[6] which are used in astrophysics, atomic physics, thin film,[7] and other fields. The WKB method[8] of reference equations was proposed based on research on the asymptotic properties of solutions by Aripov.[9] Professor Aripov identified the following new effects (Phenomenon) depending on the value of numerical parameters for the nonlinear parabolic type equations[10] and their systems: finiteness of heat propagation[11] speed, spatial localization of bounded and unbounded (blow-up[12]) solutions, cooling of temperature at finite time, one-sided front and The observation of phenomena such as the appearance of "wall" phenomena was proved for the first time.
Aripov and his students determined the above-mentioned new properties of mathematical models described by Cauchy[13] and boundary value[14] problems for nonlinear degenerate[15] equations of parabolic type and their systems. In particular, they include porous medium, generalized p-Laplacian[16][17] equations, filtration processes in gases and liquids, nonlinear diffusion,[18] heat conduction,[19] convective migration of dust and salts in one- and multi-component nonlinear mediums, and nonlinear biological population[20] processes of variable density Kolmogorov-Fisher type.[21][22] Methods for researching the properties of mathematical models expressed by double nonlinear equations[23][24] based on the self-similar approach[25][26] are proposed.
Aripov made a worthy contribution to the development of mathematical modeling,[27] information security,[28] and information technology areas, and more than 200 of his scientific articles on these areas were published in prestigious journals and Republican journals abroad.
Aripov adequately represented Uzbek science[29] outside the borders of our republic, giving scientific reports at more than 50 international congresses and scientific conferences held in foreign countries around the world. He is the organizer of the ongoing international scientific conference Al-Khwarizmi[30] and a member of the organizing committee of many international conferences. He has also organized more than 10 other international conferences with the participation of famous scientists around the world. He wrote over 50 books[31] and study guides with his students, of which four were awarded as the best books.
Member of the scientific societies[edit]
As a member of the scientific societies "Mathematics" of the USA[32] and Europe the Society for Applied Mathematics and Mechanics (GAMM,[33] Germany), ISAAC, and TWMS, a reviewer of Zentralblatt,[34] a member of the editorial board of the international journals "Pure and Applied Mathematics", "Information Security",[35] etc., Aripov actively deals with scientific cooperation with leading universities and research centers around the world. As a result of cooperation under the leadership of Aripov, four projects of theEuropean Union (CLASS,[36] COCUZ, CANDI,[37] and WATER[38]) and Russia-Uzbekistan research projects were completed.
Cooperation in organizations[edit]
Aripov was the coordinator[39] of the Еrasmus +[40] project (2017–2020), as a result of which the training of masters[41] in the new specialty "Computational Linguistics" will be carried out. Also, Aripov was the coordinator and initiator of the COCUZ project at the CANDI National University of Uzbekistan, Urgench State University,[42] and Tashkent Chemical-Technological University[43] in 2005–2013.
In 1972–1982, when he headed the Computing Center of Tashkent State University, under his scientific supervision, the subsystems "Abiturient[44]", "Student", "Session", and "Library Acquisition" of the ASC of the university were developed and introduced at Tashkent State University and in several other universities in the Republic.
