Lower Semicontinuity of Weighted Path Length in Bv

چکیده

We establish some basic lower semicontinuity properties for a class of weigthed metrics in BV. These Riemann-type metrics, uniformly equivalent to the L 1 distance, are deened in terms of the Glimm interaction potential. They are relevant in the study of nonlinear hyperbolic systems of conservation laws, being contractive w.r.t. the corresponding ow of solutions.

and of the corresponding extension (1.3) to BV (Ω), with the aim of understanding which are the minimal assumptions on f that guarantee lower semicontinuity. Here, the starting point is the result, proved in [20], stating that if the integrand f(x, u, ξ) is a nonnegative, continuous function from Ω× IR× IR , convex in ξ, and such that the (classical) derivatives ∇xf,∇ξf,∇x∇ξf exist and are cont...

A new L1-lower semicontinuity result

The aim of this work is to prove a chain rule and an L1-lower semicontinuity theorems for integral functional defined on BV (Ω). Moreover we apply this result in order to obtain new relaxation and Γ-convergence result without any coerciveness and any continuity assumption of the integrand f(x, s, p) with respect to the variable s. Sunto. L’obiettivo di questo lavoro é quello di dimostrare una n...
