Original Announcement

This workshop will be devoted to the study of Weinstein manifolds from the perspective of their skeleta. Weinstein manifolds are fundamental building blocks in symplectic geometry, generalizing the key example of cotangent bundles. Notably, they come equipped with singular isotropic skeleta generalizing the smooth zero-section of a cotangent bundle. The focus of the workshop will be on the construction and application of skeleta with arboreal singularities, mild singularities of a combinatorial nature. Such skeleta offer a natural generalization of smooth manifolds, and the workshop will develop their theory in order to study the symplectic topology of their surrounding Weinstein manifolds.

The main topics for the workshop are:

Material from the workshop

A list of participants.

The workshop schedule.

A report on the workshop activities.

A list of open problems.
