We organise an Autumn Workshop on Algebraic Combinatorics,
which aims to create a good opportunity for senior and young mathematicians in the field to exchange their ideas.
All scientific activities will take place at the School of Mathematical Sciences of Hebei Normal University
on November 8-9, 2025 (November 7 is the day to arrive and November 10 is the day to leave, that is, there will be
no activities on these days).
The working language of the event is English.
The program of the event consists of eighteen 40-minute invited talks.
