Relaxation and Integral Representation for Functionals of Linear Growth on Metric Measure Spaces
نویسنده
چکیده
This article studies an integral representation of functionals of linear growth on metric measure spaces with a doubling measure and a Poincaré inequality. Such a functional is defined through relaxation, and it defines a Radon measure on the space. For the singular part of the functional, we get the expected integral representation with respect to the variation measure. A new feature is that in the representation for the absolutely continuous part, a constant appears already in the weighted Euclidean case. As an application we show that in a variational minimization problem related to the functional, boundary values can be presented as a penalty term.

Coupled fixed point on ordered cone metric spaces with application in integral equations
Our theorems are on ordered cone metric spaces which are not necessarily normal. In the end, we describe the application of the main results in the integral equation.Although Du in [W. S. Du, A note on cone metric fixed point theory and its equivalence, Nonlinear Analysis, 72(2010) 2259-2261.], showed that the fixed point results in the setting of cone...

A representation formula for the relaxation of integral energies (u, v) 7→ ∫ Ω f(x, u(x), v(x)) dx, is obtained, where f satisfies p-growth assumptions, 1 < p < +∞, and the fields v are subjected to space-dependent first order linear differential constraints in the framework of A -quasiconvexity with variable coefficients.
