Symplectic Geometry and Special Metrics

Scope of the special session

This special session will be devoted to research topics in symplectic geometry and special holonomy; in particular, metrics with exceptional holonomy G2 or Spin(7), and quaternionic Kähler metrics. The participants will be given the opportunity to exchange ideas and knowledge, identify open problems and start new collaborations, setting the foundations to explore new lines of research.
