15 July – Arunima Ray: Embedding surfaces in 4-manifolds

The talk will consider the following question: when is a given map of a surface to a 4-manifold homotopic to an embedding? Arunima Ray will give a survey of related results, including the celebrated work of Freedman and Quinn, and culminating in a general surface embedding theorem, arising in joint work with Daniel Kasprowski, Mark Powell, and Peter Teichner. Arunima Ray is a Lise Meitner researc...

6-7 July – Ludovic Tangpi: A probabilistic approach to the convergence of large population games to mean field games (Mini-Seminar Series)

Mean field games are infinite population idealizations of Nash equilibrium problems in symmetric, finite population games in the microscopic regime. They present enormous advantages, and their study has given rise to an imporant literature over the past decade with striking applications. Coming from AIMS South Africa, Ludovic Tangpi started his doctorate as a BMS student at HU Berlin under direct...

1 July – Irit Dinur: P, NP, and Probabilistically Checkable Proofs

Dinur will talk about the PCP theorem and its many applications, and end by touching upon a surprising recent connection between PCPs and the so-called high-dimensional expanders, which are objects that come from pure math. The talk is also part of the Millennium Festival: Irit Dveer Dinur is a full professor at the Weizmann Institute of...

Celebrating Math

After too long a break, we invite you to celebrate Math with the MATH+ community. As part of the German-wide event series "The 7 Greatest Mathematical Adventures", we present a diverse program of talks and activities around the famous Millennium Prize Problem “P versus NP”.
