Huawei-IHÉS Workshop on Mathematical Sciences

As part of the IHES-Huawei partnership, this one-day workshop is organised by the Huawei's Mathematical and Algorithmic Sciences Lab jointly with IHÉS and aims at creating scientific exchanges around mathematical topics that are essential for the development and innovation of the ICT.

Riemannian Geometry Past, Present and Future: an homage to Marcel Berger

Marcel Berger greatly contributed to mathematics, through his own publications, for example on holonomy groups, symmetric spaces, curvature pinching and the sphere theorem, spectral geometry or systolic geometry. His influence goes far beyond his research papers. His books and surveys have inspired not only his students, but a much broader audience. Important features of Marcel Berger's mathematical heritage are also his seminar and his influence on the round tables organized by his friend Arthur L. Besse. Marcel Berger's Riemannian geometry seminar held at the Universite Paris VII in the nineteen-seventies and eighties, hosted lectures by both reputable mathematicians and young researchers. For the participants, it was a unique place for lively and informal mathematical discussions and exchanges, as well as inspiration.

Editor's Note: Claude LeBrun has kindly assembled this memorial for Marcel Berger.

Huawei-IHES Workshop on Mathematical Theories for Information and Communication Technologies

As part of the IHES-Huawei partnership, this one-day workshop is organised by the Huawei's Mathematical and Algorithmic Sciences Lab jointly with IHES and aims at creating scientific exchanges around mathematical topics that are essential for the development and innovation of the ICT. The topic of this year is on the potential of the mathematics of Artificial Intelligence for breakthrough results in the ICT field

 

Resurgence in Mathematics and Physics

Resurgence in Mathematics and Physics

The aim of the conference is to facilitate an interaction between mathematicians and physicists interested in the phenomenon of resurgence, when apparently divergent series correspond to germs of analytic functions in sectors via Borel summation.

We hope that such interaction will bring new ideas in both subjects explaining e.g. analyticitity with respect to various perturbative parameters in physics, convergence of instanton corrections in symplectic topology,  the role of the wall-crossing formulas in resurgence, etc.

Google matrix: fundamentals, applications and beyond

 

The workshop will address fundamental features that determine the efficiency and control of information flow on directed networks,information retrieval, including also such fundamental properties of Google matrix as the fractal Weyl law, Anderson localization transitionfor Google matrix eigenstates.

The highlights and future developments of this research fieldwill be analyzed 20 years after the seminal article of Brin and Page (1998).

*-Keywords: Markov chains, complex networks, Google matrix,  information and financial flows, Wikipedia and cancer networks, recommender systems
