Let D be a convex subset of Rn and let f : D → R be a function. Then. 1. f is quasiconcave iff the function −f is quasiconvex. 2. f is strictly quasiconcave ...

is strictly quasiconvex. That is, strict quasiconvexity requires that a point directly between two other points must give a lower value of the function than one ...

Just as there are strictly convex functions there are strictly quasiconvex func- tions and the weird intermediate case of explicitly quasiconvex functions.
