Abstract
Generalizing the concept of Choquet simplex, we study a new class of convex solids in which satisfy the following condition: all -dimensional intersections of the form , , belong to at most finitely many homothety classes of convex solids. Our description of this class uses new results on boundedly polyhedral sets.
