# In Memoriam

UBC Mathematics honours the memory of our former faculty members

#### Professor Fred Brauer

Fred Brauer graduated from the University of Toronto in 1952, and completed his PhD at MIT in 1956. He was a professor of Mathematics at the University of Wisconsin, Madison, from 1960 to 1996, where he also served as department Head. After retirement, Prof. Brauer started a new career as an honorary professor in Mathematics at the University of British Columbia, where he became an active member of the Mathematical Biology group until his death in 2021.

Fred was a pioneer in mathematical epidemiology, continuing to carry out an active program of research and to publish papers until his recent illness. Fred trained numerous students, mentored young scientists, contributed to organization of workshops, and wrote ten books. Prof. Brauer's most recent book, published in 2019 with two coauthors is Mathematical Models in Epidemiology (Springer).

Fred is greatly missed by many of us who enjoyed his wisdom and breadth of knowledge, as well as his special sense of humour, his kindness, and his friendship.

#### PROFESSOR EDMOND GRANIRER

Eddie was born in Romania, emigrated to Israel in 1950 and received his Ph.D. at Hebrew University in 1962 under Harry Kesten. His thesis treated the measure theoretic properties of amenable semigroups, an area he returned to many times in his long research career. He was active in research until his death. In fact, his last paper was published after he died. A member of the Royal Society of Canada, Eddie's main area was the general theory of locally compact groups. He was known for his warm, ironic sense of humour, which was inherited by his son David, a well known stand up comedian and author.

#### Professor Dominik Schoetzau

Dominik obtained his PhD from ETH Zurich, working under the supervision of Christoph Schwab. After completing a postdoctoral fellowship in Minnesota, he joined the Department of Mathematics at UBC in 2003. The main area of his expertise was numerical methods for partial differential equations, and in particular, finite element methods. He was a world-renowned expert in discontinuous Galerkin (DG) methods, and made significant contributions that turned those techniques into a powerful and broadly used family of methods. Dominik published several influential papers on error and convergence of DG methods, providing rigorous analysis for establishing their utility. He also made significant contributions on the efficient numerical solution of finite element discretizations of Maxwells equations and incompressible magnetohydrodynamics problems. Despite his health struggles, Dominik continued to produce impactful mathematical results in the last several years. One of his last research projects produced a sequence papers proving exponential convergence of hp-FEM for elliptic problems in polyhedral domains.

Dominik was a warm person, husband and father. A brilliant mathematician, his outstanding contributions in the field of numerical analysis will be long lasting.
