Pekka Tukia

Pekka Tukia is a Finnish mathematician[1] who does research on Kleinian groups and their geometric properties (such as limit sets).

Tukia received his PhD in 1972 with thesis advisor Kaarlo Virtanen in Helsinki.[2] Tukia is a professor at the University of Helsinki.

He made substantial contributions to the collective work of about a dozen mathematicians who proved the Seifert fiber space conjecture.[3] In 1992 he was an invited speaker with talk Generalizations of Fuchsian and Kleinian groups at the European Congress of European Mathematicians in Paris. In 1994 he was an invited speaker with talk A survey of Möbius groups at the International Congress of Mathematicians in Zurich.

gollark: There's a UBPorts GSI.
gollark: Oh, a decent amount, they can use the APIs.
gollark: VoLTE does *not*, and neither does FM radio for some reason, but basically everything else works fine on sane devices.
gollark: With Treble, your phone vendor provides a vendor image on one partition containing something or other, and that provides a bunch of APIs to Android, and thus you can flash a generic system image onto any supported device and basically everything works.
gollark: Well, yours is old, although I think it has good custom ROM availability.
