      Mark Sapir: Subgroups of the R.Thompson group

      29th April, 2022
      Watch LaterRemove Cinema Mode

      This is joint work with Gili Golan-Polak. We describe the so-called closed subgroups of F. In particular, we construct a subgroup of F with easily decidable membership problem and undecidable conjugacy problem.

      This video was produced by the Universidade de São Paulo, as part of the LieJor Online Seminar: Algebras, Representations, and Applications.
