Let \(M=G / K\) be a simply connected symmetric space of non-positive curvature. We establish a natural 1-1-correspondence between geodesically convex \(K\)-invariant functions on \(M\) and convex functions, invariant under the Weyl group, on a Cartan subspace.

A (finite or infinite) graph G is strongly dismantlable if its vertices can be linearly ordered x o ..... x~ so that, for each ordinal fl < ~, there exists a strictly increasing finite sequence (i~)0~<j~<n of ordinals such that i o = fl, i, = ct and xi~ +1 is adjacent with x~j and with all neighbors

In this paper we consider the class of s-Orlicz convex functions defined on a s-Orlicz convex subset of a real linear space. Some inequalities of Jensen's type for this class of mappings are pointed out.
