Mikhail Katz

Mikhail "Mischa" Gershevich Katz (born 1958) is an Israeli mathematician and a professor of mathematics at Bar-Ilan University. He is well known for his work in several areas of math, including differential geometry, geometric topology, nonstandard analysis, and mathematics education.

Katz has written an important book called Systolic Geometry and Topology, which focuses on systolic geometry. One of his notable contributions to mathematics is the Katz–Sabourau inequality, named after him and another mathematician, Stéphane Sabourau. His work helps advance our understanding of shapes and spaces in mathematics.

Biography

Mikhail Katz was born in Chișinău in 1958. In 1976, he moved with his mother to the United States.

Katz earned a bachelor's degree in 1980 from Harvard University. He later studied at Columbia University, where he received his Ph.D. in 1984. He then taught at several universities before moving to Bar-Ilan University in 1999.

Work

Mikhail Katz has done important research in a part of math called systolic geometry. He worked with several other mathematicians and wrote papers for many math journals. He also helped write a book called Metric Structures for Riemannian and Non-Riemannian Spaces.

Katz wrote a book in 2007 called Systolic Geometry and Topology, which is very important in this area of math. Recently, he has also worked on how to teach math better, including new ideas about the number 0.999....
