Robert "Bob" Stephen Strichartz (October 14, 1943 – December 19, 2021) was an American mathematician who specialized in mathematical analysis.
[1] Strichartz received his PhD in 1966 from Princeton University under Elias Stein with thesis Multipliers on generalized Sobolev spaces.
He met his wife, Naomi Richardson, a ballet dancer from Brooklyn and daughter of a mathematician, in 1967.
Strichartz estimates are named after him due to his application of such estimates to harmonic analysis on homogeneous and nonhomogeneous linear dispersive and wave equations; his work was subsequently generalized to nonlinear wave equations by Terence Tao and others.
An amateur composer, he was also the driving force behind a tradition of annual math department concerts, during which faculty, students, spouses and children would perform music at all levels.
