WebStanford University Web11.5 Theorem (horizon functions as support functions). Let f : IRn → IR be proper, lsc and convex. The horizon function f∞ is then the support function of domf∗, whereasf∗∞ is the support function of domf. Proof.

In differential geometry, Fenchel's theorem is an inequality on the total absolute curvature of a closed smooth space curve, stating that it is always at least . Equivalently, the average curvature is at least , where is the length of the curve. The only curves of this type whose total absolute curvature equals and whose average curvature equals are the plane convex curves. The theorem is named after Werner Fenchel, who published it in 1929.
