Nonsmooth KKT-type optimality and duality for multiobjective fractional bilevel optimization via tangential subdifferentials

This paper studies a class of nondifferentiable multiobjective fractional bilevel optimization problems. Under suitable nonsmooth constraint qualifications, necessary optimality conditions of the Karush– Kuhn–Tucker (KKT) type are established using tangential subdifferentials. Su...

A Study of Constrained Fractional Optimization Problems Involving Interval-Valued Functions

This study explores the optimality criteria for a class of fractional optimization problems characterized by interval-valued objective functions under constraints. These problems involve curvilinear fractional integral cost functionals that are path-independent and fundamentally...

ON CONTROLLED FRACTIONAL VARIATIONAL INEQUALITIES INVOLVING CONVEX FUNCTIONALS

Abstract This paper explores weak sharp solutions for a controlled variational inequality governed by a convex fractional curvilinear integral functional with path-independent properties. The fractional framework involves derivatives or integrals of non-integer order, which intro...
