Menachem Magidor
Menachem Magidor ( Hebrew מנחם מגידור; * January 24, 1946 in Petah Tikva , Israel ) is an Israeli mathematician who specializes in axiomatic set theory and mathematical logic .
Magidor received his PhD in 1973 from Azriel Levy at the Hebrew University in Jerusalem ( On Super Compact Cardinals ). He was later a professor at the Hebrew University and its president until 2008.
Magidor made important contributions to the theory of large cardinal numbers , the arithmetic of cardinal numbers and singular cardinal numbers , the forcing method and non-monotonic logic. He was involved in the negative solution of the conjecture of singular cardinal numbers, an important problem in set theory (with Karel Prikry , Jack Silver , W. Hugh Woodin , Saharon Shelah , William J. Mitchell , Moti Gitik ). The conjecture is that the smallest cardinal number for which the Generalized Continuum Hypothesis does not hold is a singular cardinal number. With Matthew Foreman and Saharon Shelah, he proved the consistency of a generalization of Martin's axiom introduced in 1988 , which they called Martin's maximum.
In 2005 he was a Gödel Lecturer ( Skolem-Löwenheim theorems for generalized logics ). In 1997 he gave the Tarski Lectures ( The Future of Set Theory: Is Gödel's Program Still Alive? ). In 1986 he was invited speaker at the International Congress of Mathematicians in Berkeley (Large cardinals and small sets: a survey). In 2016 he was elected a member of the American Academy of Arts and Sciences .
