DOI: 10.1007/s00181-017-1232-7
Abstract: In this paper we extend the slack-based directional distance function introduced by Färe and Grosskopf (Eur J Oper Res 200(1):320–322, 2010) to measure efficiency in the presence of bad outputs and illustrate it through an… read more here.

DOI: 10.1007/s10898-020-00889-w
Abstract: We provide definitions for Fréchet $$\varepsilon $$ ε -subdifferential and Fréchet $$\varepsilon $$ ε -normals set for functions and sets in the Riemannian manifolds. Then we generalize the notions of Mordukhovich sequential subdifferential and normal… read more here.

DOI: 10.3934/cpaa.2021076
Abstract: The Hadamard semidifferential calculus preserves all the operations of the classical differential calculus including the chain rule for a large family of non-differentiable functions including the continuous convex functions. It naturally extends from the \begin{document}$… read more here.
