Abstract
Inequalities are identified for subadditive (superadditive) functions of supermodular (submodular) functions. A simple adaptation yields ine qualities for submultiplicative (supermultiplicative) compositions of log-supermodular (log-submodular) functions. Inequalities are also dev eloped when the order of composition is reversed. (C) 1998 Academic Pr ess.
