Sir Simon Kirwan Donaldson is an English mathematician known for his work on the topology of smooth (differentiable) four-dimensional manifolds, Donaldson–Thomas theory, and his contributions to Kähler geometry. He is currently a permanent member of the Simons Center for Geometry and Physics at Stony Brook University in New York, and a Professor in Pure Mathematics at Imperial College London.
Edward Charles "Ted" Titchmarsh was a leading British mathematician.
Irving Kaplansky was a mathematician, college professor, author, and amateur musician.
Bernt Karsten Øksendal is a Norwegian mathematician. He completed his undergraduate studies at the University of Oslo, working under Otte Hustad. He obtained his PhD from University of California, Los Angeles in 1971; his thesis was titled Peak Sets and Interpolation Sets for Some Algebras of Analytic Functions and was supervised by Theodore Gamelin. In 1991, he was appointed as a professor at the University of Oslo. In 1992, he was appointed as an adjunct professor at the Norwegian School of Economics and Business Administration, Bergen, Norway.
Joseph Leonard Walsh was an American mathematician who worked mainly in the field of analysis. The Walsh function and the Walsh–Hadamard code are named after him. The Grace–Walsh–Szegő coincidence theorem is important in the study of the location of the zeros of multivariate polynomials.
Eliezer 'Leon' Ehrenpreis was a mathematician at Temple University who proved the Malgrange–Ehrenpreis theorem, the fundamental theorem about differential operators with constant coefficients. He previously held tenured positions at Yeshiva University and at the Courant Institute at New York University.
Hans F. Weinberger was an Austrian-American mathematician, known for his contributions to variational methods for eigenvalue problems, partial differential equations, and fluid dynamics.
Sigurdur Helgason is an Icelandic mathematician whose research has been devoted to the geometry and analysis on symmetric spaces. In particular, he has used new integral geometric methods to establish fundamental existence theorems for differential equations on symmetric spaces as well as some new results on the representations of their isometry groups. He also introduced a Fourier transform on these spaces and proved the principal theorems for this transform, the inversion formula, the Plancherel theorem and the analog of the Paley–Wiener theorem.
Shmuel Agmon is an Israeli mathematician. He is known for his work in analysis and partial differential equations.
Israel Michael Sigal is a Canadian mathematician specializing in mathematical physics. He is a professor at the University of Toronto Department of Mathematics.
Paul Charles Rosenbloom was an American mathematician.
Ellis Bagley Stouffer was an American mathematician specializing in projective differential geometry.
Halsey Lawrence Royden, Jr. was an American mathematician, specializing in complex analysis on Riemann surfaces, several complex variables, and complex differential geometry. Royden is the author of a popular textbook on real analysis.
Ernst Alfred Ruh, born 23 February 1936, is a Swiss mathematician, specializing in differential geometry.
Richard Burt Melrose is an Australian mathematician and professor at the Massachusetts Institute of Technology who works on geometric analysis, partial differential equations, and differential geometry.
Menahem Max Schiffer ) was a German-born American mathematician who worked in complex analysis, partial differential equations, and mathematical physics.
