Public lists managed by Dhruv Ranganathan

• Algebraic Geometry Seminar
• Geometry and Topology colloquium

Talks given by Dhruv Ranganathan

Obviously this only lists talks that are listed through talks.cam. Furthermore, this facility only works if the speaker's e-mail was specified in a talk. Most talks have not done this.

• Chip-firing on graphs and the geometry of Riemann surfaces
• Degenerations of the Hilbert scheme and tropical geometry

Talks organised by Dhruv Ranganathan

This list is based on what was entered into the 'organiser' field in a talk. It may not mean that Dhruv Ranganathan actually organised the talk, they may have been responsible only for entering the talk into the talks.cam system.
