Subject: Pieter Hofstra

Message-ID: <E1nlySr-0003Pv-AW@rr.mta.ca> (raw)

It is with great sadness that we announce that our dear friend and
colleague Pieter Hofstra (1975-2022) passed away unexpectedly on May 1.
Pieter obtained his PhD from Utrecht University, under Jaap van Oosten,
studying realizability toposes. His research interests included general
topos theory, realizability, inverse semigroups and groupoids, abstract
computability, and homotopy type theory. Among his recent works, with J.
Funk he introduced the notion of isotropy groups of toposes, which he was
actively developing with students and colleagues.

While Pieter was a brilliant researcher, a kind teacher and a caring
supervisor, we will most remember him as a friend. When we have any
details for a memorial service, we will pass them along.

Richard Blute, Simon Henry, Philip Scott  (University of Ottawa)
