Morrey's problem in $R^{2 \times 4}$ and $R_{sym}^{3 \times 3}$

Andrea Agazzi, Giuseppe Bruno, André Guerra +1

We find an explicit rank-one convex non-quasiconvex integrand in $R^{2 \times 4}$ : to falsify the quasiconvexity inequality, we exhibit a map $T^{4} \to R^{2}$ …

On the sharp HÃ¶lder exponent in the De Giorgi--Nash--Moser theory

AndrÃ© Guerra

We consider solutions of uniformly elliptic equations with measurable coefficients. We assume that the lowest eigenvalue of the coefficient matrix is at least $K^{- 1}$ and the larg…
