Aripov Mersaid

Mersaid Aripov (born 20 September 1939) is an Uzbek mathematician, informatics, theoretical astrophysicist and author of several scientific monographs in the field of blow-up solution theory.
==Early life and education==
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, M. Aripov received a Doctor of Science in physics and mathematics.
==Career==
Mersaid Aripov started work at the National University of Uzbekistan in 1961 as a senior laboratory assistant. In a 63 year career he progressed to become a researcher, senior lecturer, associate professor, professor, head of the department, and chairman of the trade union committee to the first vice-rector of the university.
In 2016–2019, he was head of the department of applied mathematics and computer analysis at the National University of Uzbekistan. In 2019 he became a professor at the Department of Applied Mathematics and Computer Analysis of the National University of Uzbekistan.
Aripov combines educational and methodological work with scientific work in the fields of applied mathematics and information technology, artificial intelligence, computational linguistics, natural language processing, and information security.
===Contributions===
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, which are used in astrophysics, atomic physics, thin film, and other fields. The WKB method of reference equations was proposed based on research on the asymptotic properties of solutions by Aripov.
Aripov identified the following new effects (phenomenon) depending on the value of numerical parameters for the nonlinear parabolic type equations and their systems: finiteness of heat propagation speed, spatial localization of bounded and unbounded (blow-uphttps://www.sciencedirect.com/science/article/pii/S0377042798001009#:~:text=If%20the%20solution%20ceases%20to,of%20its%20derivatives%20become%20singular.) 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 and Boundary value problems for nonlinear degenerate equations of parabolic type and their systems. In particular, they include porous medium, generalized p-Laplacian equations, filtration processes in gases and liquids, nonlinear diffusion, heat conduction, convective migration of dust and salts in one- and multi-component nonlinear medium, and nonlinear biological population processes of variable density Kolmogorov-Fisher type.https://people.maths.ox.ac.uk/trefethen/pdectb/fisher2.pdf Methods for researching the properties of mathematical models expressed by double nonlinear equations based on the self-similar approachhttps://www.sciencedirect.com/science/article/pii/S1815385214000364#:~:text=A%20self%2Dsimilar%20solution%20is,0%20is%20an%20arbitrary%20constant. are proposed.
Aripov contributed to the development of mathematical modeling, information security, and information technology areas, and more than 200 of his scientific articles on these areas were published in journals and Uzbek journals abroad.
Aripov represented Uzbek science outside the republic, giving scientific reports at more than 50 international congresses and scientific conferences. He is the organizer of the ongoing international scientific conference Al-Khwarizmi 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 and study guides with his students, of which four were awarded as the best books.
===Member of the scientific societies===
As a member of the scientific societies "Mathematics" of the USA and Europe the Society for Applied Mathematics and Mechanics (GAMM, Germany), ISAAC, and TWMS, a reviewer of Zentralblatt, a member of the editorial board of the international journals "Pure and Applied Mathematics", "Information Security", etc., M. Aripov actively deals with scientific cooperation with leading universities and research centers around the world. As a result of cooperation under the leadership of M. Aripov, four projects of the European Union (CLASS, COCUZ, CANDI, and WATER) and Russia-Uzbekistan research projects were completed.
===Cooperation in organizations===
Aripov was the coordinator of the Erasmus+ project (2017–2020), as a result of which the training of masters in the new specialty of computational linguistics will be carried out.
He was the coordinator and initiator of the COCUZ project, CANDI National University of Uzbekistan, Urgench State University, and Tashkent Chemical-Technological University in 2005–2013.
In 1972–1982, when he headed the Computing Center of Tashkent State University, under his scientific supervision, the subsystems "Abiturient", "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.
