Abstract
The nonlinear fractional programming problem is considered. The functi ons involved in the objective function and constraints are assumed to be invex and differentiable. It is shown that the ratio of invex funct ions is invex. Sufficient optimality and duality theorems art: present ed for an invex fractional programming problem. (C) 1997 Academic Pres s.
