- Sergei P. Kurdyumov
**Sergei Pavlovich Kurdyumov**(Russian: Сергей Павлович КурдюмовNovember 18 ,1928 –December 2 ,2004 ) was a specialist in mathematicalphysics ,mathematical modeling ,plasma physics ,complexity studies and synergetics fromMoscow ,Russia .Kurdyumov graduated from the

Moscow State University in 1957. Since 1953 he worked in theKeldysh Institute of Applied Mathematics . He was also the Head of the Applied Mathematics Department in theMoscow Institute of Physics and Technology . Since 1984 he was a corresponding member of theRussian Academy of Sciences .Author and co-author of more than 300 scientific works published in Russia and abroad, including about ten monographs.

Co-author of scientific discovery of a new physical effect “Effect of T-layer” (certificate of authorship No.55 from 1969).

Pioneer design-theoretical works in the field of nuclear power engineering, laser thermonuclear fusion, laser thermochemistry were carried out by him in person and under his direction. Methods of exploration of laser thermonuclear targets by means of computational experiments were elaborated by S.P. Kurdyumov (together with academician RAS A.A. Samarskii). These methods laid the foundation for the conception of low-entropic compression of shell targets and substantiated this conception which is generally accepted nowadays all over the world.

S.P. Kurdyumov made an important contribution to the elaboration of fundamental problems of synergetics as well as to the theory of non-linear evolutionary equations. For quasi-linear equations of heat conductivity with a source, a theory of blow-up regimes has been developed by Prof. Kurdyumov and his disciples. A spectrum of eigenfunctions of an open non-linear medium is studied, properties of diffusive chaos are investigated. The theory of blow-up regimes is extended to compressible media, to the problems of dissipative and magnetic hydrodynamics. These results have found an important application and experimental confirmation in the problems connected with the laser thermonuclear fusion, in experiments on thermochemistry. From 1983 to 2004 under the direction of the Corresponding Member of the RAS S.P. Kurdyumov and with his immediate assistance, a number of fundamental scientific results in the field of mathematical physics, nonlinear dynamics and synergetics have been obtained. New methods of constructive analysis of solutions of a wide class of non-linear parabolic equations with sources and sinks are developed.

The research results in the field were presented, in particular, in the monograph entitled “Blow-up in quasi-linear parabolic equations”, Berlin: Walter de Gruyter, 1995 (in co-authorship with A.A. Samarskii, V.A. Galaktionov, A.P. Mikhailov) which has obtained the worldwide recognition. A series of pioneer works connected with analysis of diffusive chaos and with complex order in systems

reaction-diffusion was accomplished; the works exert a great influence upon the development of studies in non-linear dynamics in Russia. The monograph “Non-stationary Structures and Diffusion Chaos”, Moscow: Nauka Publishers, 1992, written in co-authorship with A.A. Samarskii, T.S. Achromeeva, G.G. Malinetskii is focused on these research results. Special attention is drawn to the application of the ideas of synergetics in such fields as strategic planning, analysis of the historical processes, the modelling of educational systems, the philosophical problems of natural sciences. Books devoted to these problems, especially, “Laws of Evolution and Self-organization of Complex Systems”, Moscow: Nauka Publishers, 1994, (in co-authorship with Helena N. Knyazeva), “Synergetics and Forecast of the Future”, Moscow: Nauka Publishers, 1997, (together with S.P. Kapitza and G.G. Malinetskii), “Foundations of Synergetics: Blow-up Regimes, Self-organization, Tempo-worlds”, Saint-Petersburg: Aletheia, 2002, (together with Helena N. Knyazeva), the collection of works of S.P. Kurdyumov and his disciples “The Blow-up Regimes. Evolution of the Idea. Laws of Co-evolution of Complex Systems”, Moscow: Nauka Publishers, 1999, are of great interest for the scientific community. S.P. Kurdyumov was a great organizator of science in Russia. From 1989 to 1999, he was Director of the Keldysh Institute of Applied Mathematics of the RAS. S.P. Kurdyumov was Member of the Bureau of the Department of Computer Science, Computer Techniques and Automation. During many years, he was President of International Computer Club, Vise-president of the National Committee on Mathematical Modelling. He was Full Member of the European Academy of Sciences. S.P. Kurdyumov was member of editorial boards of five Russian and international scientific journals. S.P. Kurdyumov carried on a great work on preparation of scientific staff.He created a whole scientific school in nonlinear dynamics and synergetics in Russia. 10 theses for a Doctor’s degree (Habilitation) and 19 Ph.D. theses were upheld under his supervision. S.P. Kurdyumov was honoured for his prominent achievements with governmental awards.

He was rewarded with government awards in Russia: the medals “For labour valour” (1956), the medal “For valiant labour” (1970), the order “Sign of honour” (1975), and the “Order of Honour” (1999).
