Dmitri Fyodorovich Egorov was a Russian mathematician. He studied potential surfaces and triply orthogonal systems, and made significant contributions to the broader areas of differential geometry and integral equations. Egorov's work influenced that of Jean Gaston Darboux on differential geometry and mathematical analysis. A theorem in real analysis, Egorov's Theorem, is named in his honor. Egorov held spiritual beliefs to be of great importance, … Wikipedia
