from Wikipedia, the free encyclopedia

Grigori Isaakowitsch Barenblatt ( Russian Григорий Исаакович Баренблатт ; born July 10, 1927 in Moscow ; † June 21, 2018 ) was a Russian applied mathematician .

Barenblatt 2005

He was the son of the virologist Nadezhda Weniaminovna Kagan, who developed a vaccine against encephalitis and who became infected and died in a laboratory accident, and of the Moscow endocrinologist Isaak Grigoryevich Barenblatt, author of a therapeutic manual that has been published many times . His grandfather was the mathematician Weniamin Kagan .

Barenblatt studied at Lomonossow University (Mekmat) with a degree in 1950 and a doctorate in 1953 under Andrei Kolmogorow . In 1957 he completed his habilitation at Lomonossow University (Russian doctorate) and received the title of professor in 1962. After receiving his doctorate, he conducted research at the Institute of Petroleum of the Soviet Academy of Sciences and from 1961 he was head of the plasticity theory department at the Institute of Mechanics at Lomonosov University. From 1975 to 1992 he headed the theoretical department in the Institute of Oceanography of the Soviet Academy of Sciences. From 1992 to 1994 he was GI Taylor Professor of Hydrodynamics at Cambridge University , and from 1994 as Professor Emeritus.

In 1990 he was visiting professor at the University of Paris VI , 1991 and 1994 visiting professor at the University of Minnesota (1994 as Hill Professor ), 1992 at the University of Rome (Tor Vergata), 1993 and 1995/6 at the Autonomous University of Madrid, 1995 on from the University of Illinois at Urbana-Champaign , 1996/97 Timoshenko visiting professor at Stanford University and the University of California, Berkeley . From 1997 he was at the Lawrence Berkeley National Laboratory and at the same time professor in Berkeley.

Among other things, he dealt with hydrodynamics in porous media (e.g. two-phase flow, crude oil, natural gas, groundwater in fissured rock), fracture mechanics, continuum mechanics of non-classical media such as polymers and turbulence . With Jakow Borissowitsch Seldowitsch he worked for a long time, for example on self-similar solutions and intermediate asymptotics (with applications in the theory of explosions and combustion and spreading of thin films). In this context he was also co-editor of the collected essays by Seldowitsch.

He was a member of the American Academy of Arts and Sciences (1975), the National Academy of Engineering , the Academia Europaea and the National Academy of Sciences . He was an external member of the Royal Society (2000) and Gonville and Caius College , Cambridge. In 1993 he received an MA (Master of Arts) from Cambridge.

He received the Tymoshenko Medal in 2005, the Modesto Panetti Prize in 1995, the GI Taylor Medal of the US Society of Engineering Science in 1999 , the Lagrange Medal of the Accademia dei Lincei in 1995 and the JC Maxwell Medal of the International Congress of Industrial and Applied Mathematics in 1999. Barenblatt was an honorary doctor of the Royal Stockholm Technical University and the Turin Polytechnic. He was a member of the Polish Society for Theoretical and Applied Mechanics and the Danish Center for Applied Mathematics and Mechanics.
