Martin Schechter (mathematician)

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.^[1][2]

Schechter did his undergraduate studies at the City University of New York.^[1]

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.^[3] He taught at NYU from 1957 to 1966, and at Yeshiva University from 1966 to 1983, before moving to UC Irvine.^[1]

He is the author of several books, including the textbook Principles of Functional Analysis (Academic Press, 1971; 2nd ed., AMS, 2002).^[4]

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.
