Walter Alexander Strauss

Walter Alexander Strauss (born 1937) is an American applied mathematician, specializing in partial differential equations and nonlinear waves. His research interests include partial differential equations, mathematical physics, stability theory, solitary waves, kinetic theory of plasmas, scattering theory, water waves, and dispersive waves.

Education and career
Strauss graduated in 1958 with an A.B. in mathematics from Columbia University and in 1959 with an M.S. from the University of Chicago. He received his Ph.D. from the Massachusetts Institute of Technology in 1962. His thesis was titled Scattering for hyperbolic equations and was supervised by Irving Segal. Strauss was a postdoctoral researcher for the academic year 1962–1963 at the University of Paris. He was a visiting assistant professor from 1963 to 1966 at Stanford University. At Brown University he was an associate professor from 1966 to 1971 and a full professor from 1971 to the present.

Strauss has done research on "scattering theory in electromagnetism and acoustics, stability of waves, relativistic Yang-Mills theory, kinetic theory of plasmas, theory of fluids, and water waves."

"He has visited, for a semester or more, each of the following: C.U.N.Y., U. of Paris, University of Tokyo, M.I.T., University of Maryland, Yunnan University, Courant Institute (NYU), University of Houston, Inst. H. Poincare (Paris), Duke University and the Mittag-Leffler Institute (Sweden). During 2000-2007 he was the Editor-in-Chief of the SIAM Journal on Mathematical Analysis. Strauss is the author of more than 100 research articles and two books."
