Nail H. Ibragimov

From 1992, he worked abroad. From 1992 to 1994 he was at Istanbul Technical University in Turkey. From 1994 to 2000 he was in South Africa, first at the University of the Witwatersrand in Johannesburg and beginning in 1997 at the University of Bophuthatswana. His last position was at the Blekinge Institute of Technology in Sweden, starting in 2000. Yvonne Choquet-Bruhat recalls that he moved from Johannesburg because his wife and daughters found life there "excessively difficult" compared to the "smaller and more peaceful" town of Mmabatho and its University of Bophuthatswana, where she visited him. In turn, she suggested to Maurice A. de Gosson that Ibragimov be invited as a speaker to an international conference in Sweden, and this led to his position working with Gosson at Blekinge.

From Novosibirsk, Ibragimov moved in 1980 to Ufa, where he directed a laboratory in mathematical physics in the Ufa Scientific Center of the Russian Academy of Sciences. At the same time, he worked as a professor of mathematics at the Ufa State Aviation Technical University, where he became chair of applied mathematics in 1984. In 1987 he returned to Moscow, where he held a position at the Keldysh Institute of Applied Mathematics and lectured at the Moscow Institute of Physics and Technology.

After Army service, he entered the Moscow Institute of Physics and Technology, but then transferred to Akademgorodok and then to Novosibirsk State University, from which he graduated in 1965. He completed a Ph.D. in 1967 in the Lavrentyev Institute of Hydrodynamics of the Siberian Branch of the Russian Academy of Sciences in Novosibirsk. His dissertation, Group properties of some differential equations, was supervised by Lev Ovsyannikov [ru; de]. He completed his Doktor nauk degree in 1973 in the Sobolev Institute of Mathematics, with the dissertation Lie groups in some problems of mathematical physics.

Nail Hairullovich Ibragimov (Russian: Наиль Хайруллович Ибраги́мов, January 18, 1939 – November 4, 2018) was a Russian mathematician and mathematical physicist. At his death he was a professor emeritus at the Blekinge Institute of Technology. Ibragimov's research area was differential calculus, group analysis and mathematical physics. He was the author of many books on mathematics and mathematical physics.

Ibragimov was born on January 18, 1939 in Urussu, in the Soviet Union (now in the Republic of Tatarstan in the Russian Federation). He later dedicated the first volume of his selected works to Larisa Petrovna Barkhat, one of his schoolteachers in Urussu, and to the other teachers there.
