Transforming the World

through Mathematics



06-08 October – Kick-off Workshop of the Thematic Einstein Semester on ”Mathematics of Imaging in Real-World Challenges”

The Kick-off Workshop of the TES in Winter Semester 2021/22 on "Mathematics of Imaging in Real-World Challenges" will take place in the Physikalisch-Technische Bundesanstalt Institute Berlin (PTB) on 06-08 October 2021. This event will bring together practitioners, biomedical engineers, computer vision and machine learning experts as well as applied mathematicians in order to exchange on the curre...

16 July – Helmut Hofer: The Floer Jungle: 35 Years of Floer Theory (Joint IAS/Princeton/Montreal/Paris/Tel-Aviv Symplectic Geometry Zoominar)

An exceptionally gifted mathematician and an extremely complex person, Floer exhibited, as one friend put it, a "radical individuality." Indeed, his revolutionary mathematical ideas, contradicting conventional wisdom, could only be inspired by such impetus, and can only be understood in this context. Helmut Hofer is the Hermann Weyl Professor at the Institute for Advanced Study (IAS) in Princeto...

2 July – Kathryn Hess: Topological insights in neuroscience

Over the past decade, research at the interface of topology and neuroscience has grown remarkably fast. In this talk, after a very brief introduction to the necessary elements of neuroscience, Hess will survey the results obtained by her and her collaborators when applying topological tools to studying the relationship between brain structure and function, primarily in collaboration with the Blue...

21 May – Martin R. Bridson: Chasing finite shadows of infinite groups through geometry

There are many situations in geometry and group theory where it is natural, convenient or necessary to explore infinite groups via their actions on finite objects. But how much understanding can one really gain about an infinite group by examining its finite images? Sometimes little, sometimes a lot. In this colloquium talk, Bridson will sketch some of the rich history of this problem. Martin Bri...

7 May – Sebastian Pokutta: Conditional Gradients in Machine Learning and Optimization

Conditional Gradient Methods are an important class of methods to minimize smooth convex functions over polytopes. In this talk, Pokutta will give a broad overview of these methods and their applications and present some recent results both in traditional optimization and learning as well as in deep learning. Sebastian Pokutta is the Vice President of the Zuse Institute Berlin (ZIB) and a Profess...

16 Apr – Maria Chudnovsky: Induced subgraphs and tree decompositions (Kovalevskaya Colloquium)

Tree decompositions are a powerful tool in structural graph theory that is traditionally used in the context of forbidden graph minors. Connecting tree decompositions and forbidden induced subgraphs has so far remained out of reach. Recently, several results in this direction have been obtained. The talk will be a survey of these results. Maria Chudnovsky received her PhD from Princeton Universi...
