Heidelberg Geometry Seminars and related events
Winter semester 2022/2023

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 1 p.m. in room SRB. Before the seminar, we usually have lunch together.

The Differential Geometry Seminar (DGS) takes place on Thursdays. When in person, we usually meet at 2 p.m. in room SR 5. Our online meetings are usually at 5 p.m., e.g. when the speaker is in a different time zone like the USA. Please see the seminar webpage for further details.

The Symplectic Geometry Seminar (SGS) takes place on Wednesdays at 11:15 in room SR 4.

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

Additional events are listed in the second table.
