## Workshop "Young Researchers in String Mathematics", November 27 - 30, 2017

**Workshop "Young Researchers in String Mathematics"**

**November 27 - 30, 2017**

The workshop is an occasion to foster interactions and initiate new collaborations between young researchers active in Germany and nearby countries, who are all interested in mathematical aspects of string theory: mirror symmetry, enumerative geometry of curves (Gromov-Witten theory, Donaldson-Thomas, stable pair invariants, ...) and their modularity, integrability, and algebraic properties, tropical geometry, topological recursion, wall-crossing phenomena and Bridgeland stability conditions, relations to gauge theory, geometric quantization, conformal field theory, etc.

## Summer School "Modular forms are everywhere"

## Young Women in Geometry

## Registration **Participants ****Practical Information**

This meeting is part of the series of workshops Young Women in...

The main lectures will be given by (**note that the list of our main speakers is updated)**

The workshop provides a platform for female graduate students and postdocs in Geometry to present their research. The main lectures will be complemented by participants' talks and a poster exhibition.

## Higher Geometric Structures along the Lower Rhine VIII

This is the eighth of a series of short workshops jointly organized by the Geometry/Topology groups in Bonn, Nijmegen, Utrecht and Leuven, all situated along the Lower Rhine. The focus lies on the development and application of new structures in geometry and topology such as Lie groupoids, differentiable stacks, Lie algebroids, generalized complex geometry, topological quantum field theories, higher categories, homotopy algebraic structures, higher operads, derived categories, and related topics.

## Workshop on Homotopy Type Theory

The workshop will give the participants the chance to discuss of current problems in areas of active research in homotopy type theory. Each day will start with a lecture series by Vladimir Voevodsky on "Dependent Type Theory", followed by open seminars in which workshop participants can give short presentations on their research.

The lecture series by Vladimir Voevodsky was recorded and can be found here .

## Seminar Aachen-Bonn-Köln-Lille-Siegen on Automorphic Forms

This is the 47th meeting of the joint French-German seminar on automorphic forms

which is organized by the universities of the five cited cities. Everybody who is interested in

automorphic forms is welcome. We encourage in particular young researchers to participate

and to report on their work in one of our meetings. For further information concerning this

meeting please send an email to moree$@$mpim$-$bonn$.$mpg$.$de

## BICMR-HCM: Beijing meets Bonn

The purpose of this workshop is to enhance scientific exchange with the German math community and also advertise the postdoc program at BICMR (Beijing International Center for Mathematical Research).

## Workshop on Homotopy theory, manifolds, and field theories

This workshop is part of our Trimester Program at the Hausdorff Institute (HIM)

## Workshop: Geometric quantization and topological recursion

**Goal:** The workshop aims at establishing bridges between the geometric quantization of moduli spaces, and the theory of the topological recursion, continuing earlier discussions initiated by some of the participants. As an application, we have in view the understanding of the all-order asymptotics of quantum knot invariants, like the knot state ensuing from the Witten-Reshetikhin-Turaev construction, or the colored Jones polynomial.

## Motivic structures on quantum cohomology and pencils of Calabi-Yau motives. Final reports

The goal is to report on the progress made since the first meeting in 2010 on a variety of subjects, including:

## Higher Geometric Structures along the Lower Rhine IV

This is the fourth of a series of short workshops jointly organized by the Geometry/Topology groups in Bonn, Nijmegen, and Utrecht, all situated along the Lower Rhine. The focus lies on the development and application of new structures in geometry and topology such as Lie groupoids, differentiable stacks, Lie algebroids, generalized complex geometry, topological quantum field theories, higher categories, homotopy algebraic structures, higher operads, derived categories, and related topics.

## Automorphic Forms Seminar Aachen-Koeln-Lille-Siegen

This is the 41st meeting of the joint French-German intercity seminar on automorphic forms. Everybody who is interested in automorphic forms is welcome. We encourage in particular young researchers to participate and to report on their work in one of our meetings. For further informations concerning this meeting please send an email to moree@mpim-bonn.mpg.de or nils.skoruppa@gmail.com.

## Bonn-Köln Number Theory and Physics Seminar

## Special talks in honor of Günter Harder's contributions to mathematics

On Friday, March 15, 2013 the Max Planck Institute for Mathematics will organize a meeting with some lectures to honor emeritus director Professor Günter Harder's important contributions to MPIM and Mathematics. On this occasion there will be talks by two of his former students. Professor Harder will turn 75 on March 14.

## Galois representations and pencils of Calabi-Yau motives

#### Details

The workshop "Galois representations and pencils of Calabi-Yau motives" will be held at the MPIM Bonn during the week 15-21 December, 2012 as part of the activity "Quantum cohomology, Frobenius manifolds and pencils of Calabi-Yau varieties" in 2012-2013.

## Hirzebruch Colloquium and Hirzebruch Lecture

The Max Planck Institute for Mathematics in Bonn mourns the death of Professor Dr. Friedrich Hirzebruch who passed away on Sunday, May 27. His 85th birthday would have been on October 17, 2012. On this occasion the University of Bonn, the Max Planck Institute for Mathematics and the University Club are holding a one-day commemorative colloquium followed by the annual Hirzebruch lecture.
