L'analyse dans les espaces métriques est un domaine des mathématiques qui s'est beaucoup développé ces dernières années. Celui-ci a de nombreuses applications, en géométrie et en synthèse d'image par exemple. Ce livre, issu de plusieurs cour

In the following paper, one studies, given a bounded, connected open set $\Omega$ $\subseteq$ R n , $\kappa$ > 0, a positive Radon measure $\mu$ 0 in $\Omega$ and a (signed) Radon measure $\mu$ on $\Omega$ satisfying $\mu$($\Omega$) = 0 and |$\mu$| $

This paper is devoted to the study of shape optimization problems for the first eigenvalue of the elliptic operator with drift L = --$\Delta$+V (x)\cdot \nabla with Dirichlet boundary conditions, where V is a bounded vector field. In the first instan

Let Ω be a smooth bounded (simply connected) domain in R n and let u be a complex-valued measurable function on Ω such that | u ( x ) | = 1 a.e. Assume that u belongs to a Besov space B p , q s ( Ω ; ℂ ) . We investigate whether there exists a r

We study the \(L^p\) boundedness of the Riesz transform as well as the reverse inequality on Riemannian manifolds and graphs under the volume doubling property and a sub-Gaussian heat kernel upper bound. We prove that the Riesz transform is then boun

In this paper, we prove some pointwise comparison results between the solutions of some second-order semilinear elliptic equations in a domain \(\Omega \) of \(\mathbb {R}^n\) and the solutions of some radially symmetric equations in the equimeasurab

International audience; Let $w\in L^1_{loc}(\R^n)$ be apositive weight. Assuming that a doubling condition and an $L^1$ Poincar\'e inequality on balls for the measure $w(x)dx$, as well as a growth condition on $w$, we prove that the compact subsets o

International audience; We give short simple proofs of Uspenskii's results characterizing Besov spaces as trace spaces of weighted Sobolev spaces. We generalize Uspenskii's results and prove the optimality of these generalizations. We next show how c
