Lafforgue's SISSA Mathematical Colloquium

[Antonio Lerario]

Dear All,

this is to announce next SISSA Mathematical Colloquium.

Speaker: Laurent Lafforgue (IHES)
Title: The creative power of categories: elements of History and some new
perspectives
When: Monday, December 14, at 4pm
Where: remotely at this link https://sissa-it.zoom.us/j/83750537199

Abstract: The notion of category and the basic language of category
theory (functors,
natural transformation of functors, limits, colimits, adjoint functors,...)
are very recent in History and may seem too simple and too general.

However, it has been proved repeatedly - especially by Grothendieck and his
followers - that these simple notions can be transformed into very powerful
means of creation of new mathematics.

The purpose of this talk will be to present some of the most powerful
category-based
ideas and theories introduced by Grothendieck. Some emphasis will be given
to the notion of topos, which Grothendieck considered its most important
idea (together with the idea of motive) and which recently has been given
new impetus by Italian mathematician Olivia Caramello's "technique of
toposes as bridges".
