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 low-dimensional topology, topology of manifolds, combinatorial topology, embedding theory, infinite-dimensional 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), 589-614). 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.
