Biography
In 1947 he graduated from Moscow State University , Faculty of Mechanics and Mathematics , in 1950 - graduate school of this faculty, subsequently remained working at the Faculty of Physics (since 1951 ). Since 1967 - Doctor of Physical and Mathematical Sciences. In 1980, together with V. A. Ilyin, he became a laureate of the USSR State Prize for the textbooks “Analytical Geometry”, “Linear Algebra” and “Fundamentals of Mathematical Analysis”.
He is the founder of the geometric direction of research at the Department of Mathematics of the Physics Department of Moscow State University. He obtained fundamental results on the theory of infinitesimal bending of surfaces, the theory of isometric immersions "in general" of two-dimensional metrics of negative and alternating curvature in Euclidean spaces. E. G. Poznyak (together with N. V. Efimov ) was the first to obtain a generalization of the famous Hilbert theorem on the non-immersibility of the Lobachevsky plane in three-dimensional Euclidean space [1] .
The achievements of the geometric school of E. G. Poznyak are the fundamental results on the geometric study of equations of the sine-Gordon and Chebyshev type - the key equations of various branches of physics, as well as the creation of a single geometric concept of nonlinear differential equations of modern mathematical physics based on Lobachevsky geometry .
