PSEUDOSPHERICAL SURFACES AND SOME PROBLEMS OF MATHEMATICAL PHYSICS

摘要

In the paper, some aspects of the interrelation of Lobachevsky geometry and nonlinear differential equations are discussed. The author devotes this paper, in which some aspects of the Lobachevsky geometry and its applications in mathematical physics are discussed, to the memory of an outstanding geometer, Professor Eduard Genrikhovich Poznyak. The name of Prof.
