Blaschke selection theorem
Blaschke compactness principle
A metric space of convex bodies is locally compact, i.e. it is possible to select, out of an infinite set of convex bodies belonging to a given cube, a sequence which converges to some convex body in this cube.
The theorem was demonstrated in 1916 by W. Blaschke .
