Lower convex envelope explained

In mathematics, the lower convex envelope

\breve f of a function f defined on an interval [a,b] is defined at each point of the interval as the supremum of all convex functions that lie under that function, i.e.\breve f (x) = \sup\{ g(x) \mid g isconvexand g \leq f over [a,b] \}.
