# Geometric Topology Fair (Past)

From w

Geometric Topology Fair in Korea is an annual conference series encompassing geometric topology, geometric group theory and dynamics. It focuses on interactions between geometric group theory and low-dimensional topology. The mini courses are particularly aimed at graduate students and early career researchers.
