In this paper, we define a Kuhn‐Tucker (KT)–pseudoinvex multidimensional control
problem. More exactly, we introduce a new condition on the functions, which are involved in …

In this paper, we introduce a new condition on functions of a control problem, for which we
define a KT-invex control problem. We prove that a KT-invex control problem is …

In this paper, we introduce the interval-valued KT-pseudoinvex variational control problems
involving multiple integral objective functionals. Specifically, a new condition of generalized …

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 article, we introduce interval-valued Kuhn–Tucker (KT)-pseudoinvex optimization
problems governed by interval-valued path-independent curvilinear integral objective …

We extend the notion of KT-invexity from mathematical programming to the classical optimal
control problem and show that this generalized invexity property is not only a sufficient …

In this paper, a new approach to analyze optimality and saddle‐point criteria for a new class
of nonconvex variational problems involving invex functions is studied. Namely, the modified …

In this article, we describe a method to deal with a multi-dimensional variational problem
with inequality constraints using an exponential penalty function. We formulate an …

In this paper we move forward in the study of duality and efficiency in multiobjective
variational problems. We introduce new classes of pseudoinvex functions, and prove that …

This work considers nonsmooth optimal control problems and provides two new sufficient
conditions of optimality. The first condition involves the Lagrange multipliers while the …
