✦ Synopsis

The nonlinear fractional programming problem is considered. The functions involved in the objective function and constraints are assumed to be invex and differentiable. It is shown that the ratio of invex functions is invex. Sufficient optimality and duality theorems are presented for an invex fractional programming problem.

Mathematical programming problems involving p r -invex functions with respect to Ξ· are considered. We introduce new classes of nonlinear programming problems, called KT-p r -invex, WD-p r -invex, and HC-p r -invex problems (where p r are some real numbers). It is shown that for these types of proble
