Large time behaviour of a class of solutions of second order conservation laws

Similarity:

% We study the large time behaviour of entropy solutions of the Cauchy problem for a possibly degenerate nonlinear diffusion equation with a nonlinear convection term. The initial function is assumed to have bounded total variation. We prove the convergence of the solution to the entropy solution of a Riemann problem for the corresponding first order conservation law.

In this paper, we study the question of existence and uniqueness of entropy solutions for a system of nonlinear partial differential equations with general anisotropic diffusivity and transport effects, supplemented with no-flux boundary conditions, modeling the spread of an epidemic disease through a heterogeneous habitat.

Entropy of eigenfunctions of the Laplacian in dimension 2

Similarity:

We study asymptotic properties of eigenfunctions of the Laplacian on compact Riemannian surfaces of Anosov type (for instance negatively curved surfaces). More precisely, we give an answer to a question of Anantharaman and Nonnenmacher [] by proving that the Kolmogorov-Sinai entropy of a semiclassical measure $μ$ for the geodesic flow $g^{t}$ is bounded from below by half of the Ruelle upper bound.

Non-commutative entropy computations for continuous fields and cross-products

Emmanuel Germain (2007)

Annales mathématiques Blaise Pascal

Similarity:

We present here two non-commutative situations where dynamical entropy estimates are possible. The first result is concerned with automorphisms of cross-products by an exact group that commute with the group action and generalizes the result known for amenable groups. The second is about continuous fields of C $^{*}$ -algebras and $C (X)$ -automorphisms. Each result relies on explicit factorization via matrices.
