Heidelberg Geometry Seminars and related events
Winter semester 2021/2022


The Geometry Seminar (GS) is the common seminar of the Research Station Geometry and Dynamics (consisting of the Differential Geometry Group and the Symplectic Geometry Group). It takes place every other Tuesday, usually at 13:00. Currently we are planning for an in person / hybrid event in room SRB.

The Symplectic Geometry Seminar (SGS) takes place on Wednesdays at 11:15 in room SR 9.

The RTG Colloquium (RTG) is organized together with people from Karlsruhe. It is part of the RTG days which take place each other Tuesday, usually alternating between Karlsruhe and Heidelberg.

Additional events are listed in the second table.
