This paper is devoted to presenting optimality conditions for the sufficiency of the maximum
principle for multiobjective optimal control problems with nonsmooth data. Such conditions …

In this paper, we consider a nonsmooth nonlinear multiobjective fractional bilevel
programming problem (MFBP) in which the objective function of the upper-level is nonlinear …

In this paper, we introduce a new class of generalized dI-univexity in which each component
of the objective and constraint functions is directionally differentiable in its own direction di …

In this paper, we unify recent optimality results under directional derivatives by the
introduction of new pseudoinvex classes of functions, in relation to the study of Pareto and …

In this paper, a class of directionally differentiable multiobjective programming problems with
inequality, equality and vanishing constraints is considered. Under both the Abadie …

In this paper, we consider a nonlinear optimistic bilevel programming problem
(NMBP)(NMBP) where the upper-level is a vector optimization problem and the lower-level …

In this paper, we use a generalized Fritz John condition to derive optimality conditions and
duality results for a nonlinear programming with inequality constraints, under weak invexity …

We study a nonlinear multiple objective fractional programming with inequality constraints
where each component of functions occurring in the problem is considered …

In this paper, we have considered a class of constrained nonsmooth multi objective
programming problem involving semi-directionally differentiable functions from a view point …

In this paper, we study Fritz John type optimality conditions for constrained nonlinear
programming in which equality and inequality constraints are together present. We introduce …
