D. F. Egorov Equations with second-order partial derivatives on two independent variables. General theory of integrals, characteristics In Russian (ask us if in doubt)/Egorov D. F. Uravneniya s chastnymi proizvodnymi vtorogo poryadka po dvum nezavisimym peremennym. Obshchaya teoriya integralov, kharakteristiki Egorov, a Russian mathematician and a member of the Academy of Sciences of the USSR, President of the Moscow Mathematical Society (1923-1930). Egorov's work relates to differential geometry, the theory of integral equations, variation calculus, and the theory of functions of a real variable. He proposed a theorem on the relationship between notions of convergence almost everywhere and the uniform convergence of the sequence of functions.
