Workshop: Geometric Topology II

Wednesday, October 21, 2026

All talks will take place at aula Edificio Central (Fakulty of Mathematics) in Room 1.2, Universidad de Sevilla.

Campus Reina Mercedes (Avda. Reina Mercedes s/n, 41012 Sevilla)

In this one-day workshop, we aim to bring together researchers and students working in geometric topology and related areas. The goal is to foster interactions across different perspectives within low-dimensional topology, geometry, and algebra, and to provide a platform for informal exchange and discussion. The talks are aimed at an audience with a basic background in algebraic topology, differential geometry, and algebra, as typically covered in introductory lecture courses. In particular, the talks will be accessible to bachelor and master students in these fields.
