Transformations by Functions in Sobolev Spaces and Lower Semicontinuity for Parametric Variational Problems

چکیده
where Q <= Rm is a bounded domain, JS?W denotes m-dimensional Lebesgue measure, (p = (. An important example due to Besicovitch [1] has indicated that the situation here is a very delicate one. For m > 2, a result of this type was obtained by Morrey [7, Theorem 9.2.1] under the additional assumption that e W^Qf n C(Q)", p> m. This estimate, together with a few additional results concerning mappings <p of this type, is presented in the first part of this note.

On a Restricted Weak Lower Semicontinuity for Smooth Functional on Sobolev Spaces
We study a restricted weak lower semicontinuity property, which we call the (PS)-weak lower semicontinuity, for a smooth integral functional on the Sobolev space along all weakly convergent Palais-Smale sequences of the functional. By the Ekeland variational principle, the (PS)-weak lower semicontinuity is sufficient for the existence of minimizers under the usual coercivity assumption. In gene...
متن کاملLower semicontinuity for parametric set-valued vector equilibrium-like problems
A concept of weak $f$-property for a set-valued mapping is introduced, and then under some suitable assumptions, which do not involve any information about the solution set, the lower semicontinuity of the solution mapping to the parametric set-valued vector equilibrium-like problems are derived by using a density result and scalarization method, where the constraint set $K$...
متن کاملOn a Restricted Weak Lower Semicontinuity for Smooth Functionals on Sobolev Spaces
This paper is motivated by a problem suggested in Müller [11] that concerns the weak lower semicontinuity of a smooth integral functional I(u) on a Sobolev space along all its weakly convergent minimizing sequences. Here we study a restricted weak lower semicontinuity of I(u) along all weakly convergent Palais-Smale sequences (that is, sequences {uk} satisfying I′(uk)→ 0). In view of Ekeland’s ...
متن کاملLower semicontinuity problems in Sobolev spaces with respect to a measure
For every finite nonnegative measure ft we introduce the Sobolev spaces W^'(Q,K) and we study the lower semicontinuity of functionals of the form where the integrand / is quasiconvex.
متن کاملSobolev spaces in metric measure spaces: reflexivity and lower semicontinuity of slope
In this paper we make a survey of some recent developments of the theory of Sobolev spaces W (X, d,m), 1 < q < ∞, in metric measure spaces (X, d,m). In the final part of the paper we provide a new proof of the reflexivity of the Sobolev space based on Γ-convergence; this result extends Cheeger’s work because no Poincaré inequality is needed and the measure-theoretic doubling property is weakene...
