Intensive Research Workshop

Workshop on Geometric Structures, Dynamics and Rigidity

August 23–25, 2026
The Westin Josun Busan
Busan, Korea

A focused workshop bringing together researchers in hyperbolic geometry, projective geometry, symplectic geometry, geometric group theory, dynamics, and rigidity.

About the workshop

Geometry across structures and dynamics

This three-day workshop provides an informal and collaborative setting for researchers to exchange recent ideas in geometric structures, dynamical systems, and rigidity theory. Particular emphasis is placed on interactions among hyperbolic, projective, and symplectic geometry.
