Expositions

• A constructive proof of Lie's third theorem for Lie algebras (handwritten notes): part I, part II. This is an exposition of the integration technique from the book by Duistermaat and Kolk, which was presented at the Integration seminar in Spring 2024.

• Symplectic groupoids in Poisson geometry
• Sheaves on topological spaces and toposes

In Slovenian:

• Stokes theorem and its use in relativity
