Courses:

In the Winter term 2020/21 I teach ``Analytische Geometrie und Lineare Algebra 1''. All material and information on this course is available on StudIP. All lectures take place online, as flipped classes.

My office hours are by appointment only, via BigBlueButton.

Stefano Ronchi (November 2020 -- ): Van Est integration of Lie algebroids.

Ilias Ermeidis (October 2020 -- ): Deformations of ideals in Lie algebroids.

Short videos on geometry:

Here and here you can find my Youtube videos on curvature of curves and surfaces, and on hyperbolic geometry. These videos were made in collaboration with Fionntan Roukema in the framework of the Crochet Hyperbolic Forest exhibition at the Festival of the Mind in 2016.
