Geometric Topology Seminar Math Department of the Higher School of Economics, Room 209, Moscow
The seminar is held by Thursdays from 14:00 to 16:50.
Topics from various areas of geometric topology, including lowdimensional topology, topology of manifolds, combinatorial topology, embedding theory, infinitedimensional topology and shape theory.
The Geometric Topology Seminar has been meeting since the
1950s at the Steklov Mathematical Institute. Until the early 70s it was led by Lyudmila
Keldysh, and the participants included Alexei Sossinsky, Alexei Chernavsky and Mikhail
Shtan'ko (more details: Russ. Math. Surv. 60 (2005), 589614). In the late 70s the seminar was resumed under Evgeny Shchepin. Active participants of the seminar included
A. Chigogidze, A. Dranishnikov, M. Zarichnyi in the 80s, P. Akhmetiev, N. Brodsky,
P. Semyonov, A. Skopenkov in the 90s, and P. Akhmetiev, A. Chernavsky, O. Frolkina,
E. Kudryavtseva, S. Melikhov, M. Skopenkov in the 00s.
