Mikhail "Mischa" Gershevich Katz (born 1958, in Chi?in?u)^{[1]} is an Israeli mathematician, a professor of mathematics at BarIlan University. His main interests are differential geometry, geometric topology and mathematics education; he is the author of the book Systolic Geometry and Topology, which is mainly about systolic geometry. The KatzSabourau inequality is named after him and Stéphane Sabourau.^{[2]}^{[3]}
Mikhail Katz was born in Chi?in?u in 1958. His mother was Clara Katz (née Landman). In 1976, he moved with his mother to the United States.^{[4]}^{[5]}
Katz earned a bachelor's degree in 1980 from Harvard University.^{[1]} He did his graduate studies at Columbia University, receiving his Ph.D. in 1984 under the joint supervision of Troels Jørgensen and Mikhael Gromov.^{[6]} His thesis title is Jung's Theorem in Complex Projective Geometry.
He moved to BarIlan University in 1999, after previously holding positions at the University of Maryland, College Park, Stony Brook University, Indiana University Bloomington, the Institut des Hautes Études Scientifiques, the University of Rennes 1, Henri Poincaré University, and Tel Aviv University.^{[1]}
Katz has performed research in systolic geometry in collaboration with Luigi Ambrosio, Victor Bangert, Mikhail Gromov, Steve Shnider, Shmuel Weinberger, and others. He has authored research publications appearing in journals including Communications on Pure and Applied Mathematics, Duke Mathematical Journal, Geometric and Functional Analysis, and Journal of Differential Geometry. Along with these papers, Katz was a contributor to the book "Metric Structures for Riemannian and NonRiemannian Spaces".^{[7]}Marcel Berger in his article "What is... a Systole?"^{[8]} lists the book (Katz, 2007) as one of two books he cites in systolic geometry.
More recently Katz also contributed to the study of mathematics education^{[9]} including work that provides an alternative interpretation of the number 0.999....^{[10]}
