Ofer gabber
Ofer Gabber ( Hebrew עופר גאבר; * May 16, 1958 ) is an Israeli mathematician who studies algebraic geometry and algebra.
Gabber received his PhD from Harvard University in 1978 with Barry Mazur ( Some theorems on Azumaya Algebras ). From 1984 he was then a mathematician at the CNRS at IHES in Bures-sur-Yvette near Paris , where he is one of the main representatives of the tradition of algebraic geometry in the sense of Alexander Grothendieck , who had worked at IHES in the 1960s. In 1982 he introduced " perverse Sheaves " with Joseph Bernstein , Pierre Deligne and Alexander Beilinson and together with them proved (via his Purity Theorem ) the Decomposition Theorem , the heavy Lefschetz theorem and a semi-simplicity theorem (for positive characteristics and Existence of a Galois group effect), a deep finding about the topology of algebraic varieties. Among other things, he dealt with the etalen cohomology of schemes . In a monograph with Lorenzo Ramero, he gave a complete treatment of almost mathematics by Gerd Faltings , which among other things influenced the perfectoid concept by Peter Scholze .
In 1981 he received the Erdős Prize . In 2011 he received the Prix Thérèse Gautier of the Academie des Sciences.
