Martin Schechter

Martin Schechter (1930, Philadelphia – June 7, 2021) was an American mathematician whose work concerned mathematical analysis (specially partial differential equations and functional analysis and their applications to mathematical physics). He was a professor at the University of California, Irvine.

Schechter did his undergraduate studies at the City University of New York.

He obtained his Ph.D. in 1957 from New York University (NYU) with Louis Nirenberg and Lipman Bers as thesis advisors; his dissertation was entitled On estimating partial differential operator in the L2-norm. He taught at NYU from 1957 to 1966, and at Yeshiva University from 1966 to 1983, before moving to UC Irvine.

Schechter was a member of the Association of Orthodox Jewish Scientists.

Schechter is buried in the Har Menuchot cemetery in the Givat Shaul neighborhood of Jerusalem, Israel.
