On the points of non-differentiability of convex functions

Comment.Math.Univ.Carolinae 45,4 (2004) 727-734.

Abstract:We characterize sets of non-differentiability points of convex functions on $\Bbb R^n$. This completes (in $\Bbb R^n$) the result by Zaj\'\i \v cek [2] which gives a characterization of the magnitude of these sets.

Keywords: differentiability, convex functions
