Abstract

We show that, if f : double struck M sign^2×2 → ℝ is rank-one convex on the Hyperboloid H_D^- := {X ∈ S^2×2 : det X = -D, X₁₁ ≥ c > 0}, D ≥ 0, S^2×2 is the set of 2 × 2 real symmetric matrices, then f can be approximated by quasi-convex functions on double struck M sign^2×2 uniformly on compact subsets of H_D ^-. Equivalently, every gradient Young measure supported on a compact subset of H_D^- is a laminate.
