Weak sharp minima for interval-valued functions and its primal-dual characterizations using generalized Hukuhara subdifferentiability

Krishan Kumar, Debdas Ghosh, Gourav Kumar

This article introduces the concept of weak sharp minima (WSM) for convex interval-valued functions (IVFs). To identify a set of WSM of a convex IVF, we provide its primal and dual…

Ekeland's Variational Principle for Interval-valued Functions

Gourav Kumar, Debdas Ghosh

In this paper, we attempt to propose Ekeland's variational principle for interval-valued functions (IVFs). To develop the variational principle, we study the concept of sequence of…
