## Due to the coronavirus, the semester cannot be held in 2020. Hopefully it will be postponed to 2021.

Mathematical physics is highly represented inside the different laboratories of the Centre Henri Lebesgue with teams working on partial differential equations, spectral theory, geometry, dynamical systems or probability. This semester aims at gathering international experts of these fields with all the members of the Centre Henri Lebesgue interested by the interactions between physics and mathematics with a special emphasis on the geometrical aspects. The semester will be organized around seven events of different nature (workshop, international conference, summer school) whose topics will cover the many facets of mathematical physics represented in the Centre Henri Lebesgue.

Besides these events, international specialists will be invited for longer stay in the different laboratories of the Centre Henri Lebesgue. A special attention will be paid to the training and to the formation of young researchers thanks to the master programs in Nantes and in Rennes but also thanks to doctoral courses given by some of our invited international experts and to two summer schools aimed for master and PhD students.
