## Friday's Séminaire Bourbaki

### June, 17 2022

This seminar was created with a thought towards younger mathematicians. Colleagues present the mathematical context of some of the talks of the Sémianire Bourbaki in order to make them more accessible; they may also introduce some tools or further motivations.
