We use the Bauer maximum principle for quasiconvex, polyconvex and rank- one convex functions to derive Krein-Milman-type theorems for compact sets in Rm x n. Further we show that in general a set of quasiconvex extreme points is not invariant under transposition and it is different from the set of rank-one convex extreme points.
