About

The International Workshop on Algebraic Topology 2026 is a five-day event which will take place at School of Mathematical Sciences of Peking University in Beijing, China, from Monday, August 17 to Friday, August 21, 2026.

The workshop brings together leading researchers and young scholars to share recent advances in algebraic topology and related fields. The week before the workshop, there will be a summer school on stable homotopy theory.
