Abstract

We study the stability of a sequence of integralfunctionals on divergence-free matrix valued fields following the directmethods of Γ-convergence. We prove that the Γ-limitis an integral functional on divergence-free matrix valued fields.Moreover, we show that the Γ-limit is also stable undervolume constraint and various type of boundary conditions.
