Abstract

We prove that convex sets are measure convex and extremal sets are measure extremal provided they are of low Borel complexity. We also present examples showing that the positive results cannot be strengthened.
Keywords: measure convex set, measure extremal set, face measure convex set, measure extremal set, face
