A general non-linear convexity theorem

, 1997
If G is a connected semisimple real Lie group with Iwasawa decomposition G = ΚΑΝ, then Kostanfs non-linear convexity theorem describes the image of a -coset a K under the mapping L: ΚΑΝ -» o, gan H* log α s the convex h ll of a Weyl group orbit of loguf.
