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 a heat physicist Samson Kutateladze.
