MATH+ Friday Colloquium   📅

Institute
Description
The Friday colloquia represent a common meeting point for Berlin mathematics: a colloquium with broad emanation that permits an overview of large-scale connections and insights. In thematic series, the conversation is about "mathematics as a whole," and we hope to be able to witness some breakthroughs. Hardly anyone knows that Grigory Perelman first presented his famous proof of the Poincaré Conjecture to the mathematical public in Berlin, at the PhD student seminar meeting of professors Huisken and Ecker at FU Berlin.
