Dmitri Yegorov

Life

Jegorow went to school in Moscow and studied mathematics and physics from 1887 at the Lomonossow University , including with Nikolai Vasilyevich Bugayev (1837-1903). He graduated in 1891 and published his first mathematical work in 1892. From 1894 he taught at the university, where he completed his habilitation in 1901 (Russian doctoral degree) and in 1903 received a professorship. In 1917 he became secretary of the Moscow Mathematical Society, in 1921 its vice-president and in 1922 its president. From 1923 he was director of the Institute of Mathematics and Mechanics at Lomonosov University. Egorov had deep religious convictions and defended the Orthodox Church , which was harshly persecuted in the 1920s , supported persecuted colleagues and resisted the spread of atheist Marxist ideology . For this reason, he was dismissed as director of the institute in 1929 and arrested soon afterwards. After the Moscow Mathematical Society refused to expel him, their leadership was changed. After a hunger strike, Egorov was transferred to the prison hospital in Kazan, where he died. It is also reported that he died in the house of Chebotaryov , whose wife was a doctor in prison.

Together with his student Nikolai Nikolajewitsch Lusin he is the founder of an influential school of real analysis in Moscow. His theorem by Jegorow (1911) makes statements about the almost uniform convergence of a point-wise μ-almost everywhere convergent sequence of measurable functions .

His students include Lusin, Iwan Georgijewitsch Petrowski , Pawel Sergejewitsch Alexandrow , Iwan Iwanowitsch Priwalow , Vladimir Vasilyevich Golubew , and Vyacheslav Vasilyevich Stepanov .
