At the end of the Leningrad University (1933) worked there, in 1952-64 Rector. Since 1964 - in the Siberian Branch of USSR Academy of Sciences. Main scientific achievements A. relate to the geometry, where he discovered methods for studying metric properties of figures that created a new object of study - t. n. irregular metric manifolds more general than Riemannian spaces. These methods have greatly improved the geometric area of research and resulted in the works A. and he created the school, to address a number of classical problems of the theory of surfaces, and also have important applications in the theory of differential equations and the theory of elastic shells. Alexandrov also belong study on the grounds of the theory of relativity and the philosophy. USSR State Prize (1942), International Prize Lobachevsky (1951). He was awarded the Order of Lenin and others. Orders and medals.
