Danuta BorowskaOn decomposition of closed, convex set theorems.
We will present Klee-Minkowski-Hirsch theorem, which states that every closed, convex set 
can be decomposed into linearity space 
, asymptotic cone 
and convex hull of extremal points of the intersection of 
and the orthogonal complement of the linearity space. We will also prove that the above theorem is a generalization of well-known results.
