An incentive to use coarse-grained models is to use them for inference and control instead of the original (often intractable) model. Since coarse-grained models are always “wrong”, questions such as inference under model misspecification or goal-oriented uncertainty quantification (e.g. for control) come into play. This workshop will address such topics, with a special focus on ...

The Dold-Thom theorem is a classical result in algebraic topology giving isomorphisms between the homology groups of a space and the homotopy groups of its infinite symmetric product. The goal of this talk is to outline a new proof of this theorem, which is direct and geometric in nature. The heart of this proof is ... Read more about "A new approach to the Dold-Thom theorem"

Let S be a compact hyperbolic surface uniformised by a Fuchsian group Γ. For any element σ ∈ G:= Gal(C/Q) the natural Galois action of G on the coefficients of the algebraic equation corresponding to the Riemann surface S yields a new hyperbolic surface S σ with uniformising group Γ σ . Little seems to ... Read more about "Galois action on compact hyperbolic surfaces and their associated solenoids."

Abstract: Let us consider a quasilattice, spanned by the superposition of two hexagonal lattices in the plane, differing by a rotation of angle ß. We study bifurcating quasipattern solutions of the Swift-Hohenberg PDE, built on such a quasilattice, invariant under rotations of angle π /3. For nearly all ß, this is a small divisor problem. ...

Abstract: In the 60s V. I. Arnold argued it was possible to apply KAM theory to the N-body problem, in the regime where one mass in much larger then the others, in turn equally sized. His statement, that goes under the name "Theorem of stability of planetary motions" has been completely proved only 50 years ...

From de Rham Cohomology to Massive Gravity Prof. Claudia de Rham (Imperial College London) De Rham Cohomology is the fundamental principle that governs any gauge symmetry and provides the building blocks for our understanding of particle physics. I will discuss how to make those dynamical for spin-1 fields and implications for spin-2 fields and gravity. ... Read more about "Journée Georges de Rham 2019"

The workshop will address computational and theoretical issues in stochastic modeling and model reduction in molecular and complex systems. In particular, the program will include topics ranging from quantum to mesoscale modelling, with focus on uncertainty quantification, machine learning and approximate inference method, methods using both quantum and classical models, semiclassical limits and their computational ...

Abstract: Columnar vortices are axisymmetric stationary solutions of the three-dimensional Euler equations, where the velocity field only depends on the distance to the symmetry axis and has no component in the axial direction. These solutions were already studied in the nineteenth century, starting with the pioneering work of Kelvin and Rayleigh, but until recently the ...

The phenomenon of KPZ (Kardar-Parisi-Zhang) universality was a very active research area in the last 10 years. One can say that it describes universal statistical properties of long directed optimal paths (geodesics) in 2D disordered environment. Apart from many physical applications, it is remarkable for extremely strong universality properties in very general setting, as well ...

The summer school will provide courses from experts in the areas of the scope of the program ''Dynamics with Structures''. It is intended to provide surveys of modern directions in the theory of dynamical systems on the level of graduate students and junior researchers. The goal is to propagate modern directions of research to younger ... Read more about "Summer School - Dynamical Systems"
