Geometry and Topology Summer School

July 5–9 2026 · Weizmann institute, Israel

The school is aimed at graduate students, postdocs and faculty that are interested in various areas of geometry and topology. Lectures are intended to be accessible, requiring only a general graduate-level background rather than specialized expertise.

Mini-courses:

Julian Chaidez (University of Southern California)
Conformally symplectic topology and dynamics

Symplectic topology is rooted in the study of dynamical systems arising from Hamiltonian mechanics. These systems are volume preserving, since they conserve the symplectic form, and they exhibit many rigidity properties, e.g. homological lower bounds on the number of periodic orbits. On the other hand, many naturally occurring dynamical systems in symplectic topology are not conservative, but instead conformally shrink and expand the symplectic form. These conformally symplectic systems include contactomorphisms and the flows of Liouville vector fields. The dynamical behavior of these systems is closely related to many open problems in symplectic topology. This mini-course will serve as an introduction to conformally symplectic dynamics and the many interesting open questions in the area.

Francesco Lin (Columbia University)
Geometry and topology of the Dirac equation

Dirac discovered his eponymous equation almost one hundred years ago while investigating relativistic quantum mechanics. Since then (the Riemannian version of) the Dirac equation has played a central role in the development of geometry and topology. In this minicourse, after introducing the basic setup of spin geometry and discussing the basic properties of the Dirac equation, we will discuss its relation with differential geometry, algebraic topology and low-dimensional topology, with concrete applications in mind.
