Born on September 21, 1899 in Lwów, he had to fight in World War I right after his graduation from school.

Italy (Italia officially the Italian Republic, (Repubblica Italiana is located on the Italian Peninsula in Southern Europe, and on the two largest He entered the university in Lwów in 1919 and received his doctorate in 1923. He got no appointment at the university and continued his research while working as teacher at a secondary school. Due to his outstanding results, he obtained a scholarship in 1932 that allowed him to spend several years in Leipzig and, especially, Paris. In Paris he started a very successful collaboration with Jean Leray. Jean Leray ( 7 November 1906 &ndash 10 November 1998) was a French Mathematician, who worked on both Partial differential Around 1935 Schauder obtained the position of a senior assistant in the University of Lwów.
Schauder was Jewish, and after the invasion of German troops in Lwów it was impossible for him to continue his work. PLEASE TAKE NOTE************ In his letters to Swiss mathematicians, he wrote that he had important new results, but no paper to write them down. He was executed by the Gestapo, probably in October 1943.

Most of his mathematical work belongs to the field of functional analysis, being part of a large Polish group of mathematicians, i. For functional analysis as used in psychology see the Functional analysis (psychology article e. Lwów School of Mathematics. The Lwów School of Mathematics (lwowska szkoła matematyczna Львівська математична школа was a group of Mathematicians who worked between the They were pioneers in this area with wide applications in all parts of modern analysis. Schauder is best known for the Schauder fixed point theorem which is a major tool to prove the existence of solutions in various problems, the Schauder bases (a generalization of an orthonormal basis from Hilbert spaces to Banach spaces), and the Leray-Schauder principle, a way to establish solutions of partial differential equations from a priori estimates. The Schauder fixed point theorem is an extension of the Brouwer fixed point theorem to Topological vector spaces such as Banach spaces. In Mathematics, a Schauder basis or countable basis is similar to the usual (Hamel basis. In Mathematics, an orthonormal basis of an Inner product space V (i This article assumes some familiarity with Analytic geometry and the concept of a limit. In Mathematics, Banach spaces (ˈbanax named after Polish Mathematician Stefan Banach) are one of the central objects of study in Functional analysis Jean Leray ( 7 November 1906 &ndash 10 November 1998) was a French Mathematician, who worked on both Partial differential In Mathematics, partial differential equations ( PDE) are a type of Differential equation, i
