New Convexity Conditions in the Calculus of Variations and Compensated Compactness Theory
Aufgrund von Vorbereitungen auf eine neue Version von KOPS, können kommenden Montag und Dienstag keine Publikationen eingereicht werden. (Due to preparations for a new version of KOPS, no publications can be submitted next Monday and Tuesday.)

| Summary: |
We consider the lower semicontinuous functional term of the form I (u) = ∫Ωf(u)dx where u satisfies a given conservation law defined by differential operator of degree one with constant coefficientsWe show that under certain constraints the well known Murat and Tartar's Λ-convexity condition for the integrand extends to the new geometric conditions satisfied on four dimensional simplexes. Similar conditions on three dimensional simplexes were recently obtained by the second author. New conditions apply to quasiconvex functions.
