In the present paper, we consider Mond-Weir type nondifferentiable second order fractional
symmetric dual programs over arbitrary cones and derive duality results under second order …

We have introduced the second-and higher-order generalised invex functions and applied it
to mathematical programming problems. Also, we have established many duality relations …

Mond-Weir and Wolfe type non-differentiable primal and dual symmetric problems in
mathematical programming are formulated. In this paper, we use a generalisation of …

In this paper, we establish the sufficient optimality conditions for minmax programming and
generalized fractional minmax programming problems. Based on the sufficient conditions, a …

In this paper, a pair of Wolfe type second-order symmetric dual non-differentiable
multiobjective programs is formulated over arbitrary cones. Weak, strong and converse …
