Groupe de travail : Sur l'homologie des groupes de Torelli

The overall goal of the working group is to understand the following paper:

[2307.07082] The second rational homology of the Torelli group is finitely generated (arxiv.org) by Daniel Minahan

This working group is organized by Erik Lindell. Below are links to the notes I took during the talks, for the people who could not make it to a session: Any mistake in the notes is my own, not the speaker’s.
