Semën Samsonovich Kutateladze
Semën Samsonovich Kutateladze (born October 2, 1945 in Leningrad, now St. Petersburg) is a mathematician. He is known for contributions to functional analysis and its applications to vector lattices and optimization. In particular, he has made contributions to the calculus of subdifferentials for vector-lattice valued functions, to whose study he introduced methods of Boolean-valued models and infinitesimals. He is professor of mathematics at Novosibirsk State University, where he has continued and enriched the scientific tradition of Leonid Kantorovich. His father was the heat physicist Samson Kutateladze.
