Characterization of generalized Orlicz spaces
Rita Ferreira, Peter Hästö, Ana Margarida Ribeiro
The norm in classical Sobolev spaces can be expressed as a difference quotient. This expression can be used to generalize the space to the fractional smoothness case. Because the d…
Existence of Minimizers for Non-Level Convex Supremal Functionals
Ana Margarida Ribeiro, Elvira Zappale
The paper is devoted to determine necessary and sufficient conditions for existence of solutions to the problem ${\rm inf}{{\rm ess sup}_{x \in Ω} f(\nabla u(x)): u \in u_0 + W^{1,…
Relaxation of certain integral functionals depending on strain and chemical composition
Ana Margarida Ribeiro, Elvira Zappale
We provide a relaxation result in , as a first step towards the analysis of thermochemical equilibria.
Lower semicontinuous envelopes in
Ana Margarida Ribeiro, Elvira Zappale
It is studied the lower semicontinuity of functionals of the type with respect to the -weak \ast topology. Moreover in absence of…
Sufficient conditions for existence of solutions to vectorial differential inclusions
Ana Cristina Barroso, Gisella Croce, Ana Ribeiro
In this paper we discuss the existence of solutions to vectorial differential inclusions. We investigate sufficient conditions for existence, more flexible than those available in…
On the existence of solutions to a nonlinear system involving isotropic deformations
Ana Cristina Barroso, Gisella Croce, Ana Ribeiro
In this paper we study the existence of solutions to an isotropic differential inclusion.
