Thomas Kappeler Explained

Thomas Kappeler (12 February 1953 – 30 May 2022) was a Swiss mathematician and professor at the University of Zurich.^{[1] [2]} Kappeler's main research was in global analysis, partial differential equations and dynamical systems in infinite dimensions.

Kappeler co-founded the Zurich Graduate School in Mathematics, a joint doctoral program of the Mathematics departments of ETH Zurich and University of Zurich.^[3] He also actively supported young kids with talent in mathematics. He was the co-leader of the children's math club Junior Euler Society.^[4]

Life

Kappeler studied mathematics at ETH Zurich, where he did his Ph.D. in 1981 under the supervision of Corneliu Constantinescu. He was a visiting professor at the University of California, Berkeley, the University of Pennsylvania, Brandeis University and Brown University. He was a professor at Ohio State University from 1990 till 1996.^[5] After that he became a mathematics professor at University of Zurich.^[6]

Selected publications

Kappeler published more than 150 research articles.^[7] He also published two books on PDEs.
