Research Institute for Mathematics and Mechanics of Moscow University (to the 100${}^{th}$ anniversary of the foundation of the Institute)

Established in November 1922, the Research Institute of Mathematics and Mechanics of Moscow University can be placed among the largest mathematical institutes in the first third of the 20th century. By its very position – a metropolitan mathematical institute with a powerful scientific potential – it became the leading mathematical institute of the Soviet Union, which determined the social life of the Soviet mathematical community. With the relocation in 1934 from Leningrad to Moscow of the Presidium of the Academy of Sciences of the USSR and the V. A. Steklov Mathematical Institute, the general situation has undergone fundamental changes – «Steklovka» became the head scientific institute in the USSR, which included leading scientists from the university research institute of mathematics and mechanics, whose work was reduced mainly to organizing postgraduate studies. At the same time, of course, we should not forget that, having transferred its leading scientists to «Steklovka», the Research Institute of Mathematics and Mechanics of Moscow University actually became one of its co-founders. And when we talk today about the history of the Steklov Institute, we must consider the history of the Research Institute of Mathematics and Mechanics of Moscow University as an integral part of it. So we are not talking about the “death” of the Institute, but about its new life, about the synthesis of the ideas of the two main Russian schools that gave life to the Soviet Mathematical School, one of the leading mathematical schools of the second half of the 20${}^{th}$ century.
