This problem naturally arises as the limiting case of a family of perturbed problems\, in which the associated Lagrangian is regularized by the gradient of a relative entropy functional. While well-posedness is well understood for the Hamilton Jacobi equation corresponding to the entropy-regularized (or perturbed) Lagrangian\, it has remained an open question whether the same viscosity techniques can be applied to the limiting\, unperturbed problem. The main contribution of this work is to show that this limiting case can be treated within essentially the same viscosity-solution framework as the perturbed caseVincent Perrolaz:Galois Connections in Hamilton – Jacobi Equations and Conservation LawsAbstract: Fabio Camilli: Kolmogorov entropy of numerical solutions for scalar conservation lawswith convex fluxAbstract:Following Lax’s information-theoretic perspective\, we study thequantitative compactness of numerical solutions to scalar conservationlaws with uniformly convex flux via Kolmogorov entropy. We prove thatconservative and monotone finite-difference schemes satisfying adiscrete one-sided Lipschitz condition preserve the optimal continuousentropy scaling established by De Lellis–Golse and Ancona–Glass–Nguyen.The upper bound stems from the discrete Lipschitz structure\, while thelower bound relies on a uniform approximation of BV functions. Thesefindings rigorously confirm the high-resolution nature of first-orderschemes in Lax’s sense. Finally\, we formulate a general transferprinciple for the lower bound and discuss its applications toinformation recovery via numerical post-processing   \nhttps://indico.math.cnrs.fr/event/17080/

SUMMARY:Michael Hitrik: Tunneling and Weyl laws for the $overline{partial}$ operator on Riemann surfaces
DESCRIPTION:We study the number of exponentially small singular values for the semiclassical $overline{partial}$ operator on exponentially weighted $L^2$ spaces on a compact Riemann surface. Accurate upper and lower bounds on the number of such singular values are established with the help of auxiliary notions of upper and lower bound weights. Assuming that the Laplacian of the exponential weight changes sign along a curve\, we construct optimal such weights by solving a free boundary problem\, which yields a Weyl asymptotics for the counting function of exponentially small singular values. We also provide a precise description of the leading term in the Weyl asymptotics\, in the regime of small exponential decay rates. This is joint work with Johannes Sjöstrand and Martin <a href="http://Vogel. \nhttps://indico.math.cnrs.fr/event/17058/ » target= »_blank » title= »Vogel. \nhttps://indico.math.cnrs.fr/event/17058/ »>Vogel. \nhttps://indico.math.cnrs.fr/event/17058/
