On Clarke’s subdifferential of marginal functions
Applied Set-Valued Analysis and Optimization · 2021
In this paper, we derive an upper estimate of the Clarke subdifferential of marginal functions in Banach spaces.The structure of the upper estimate is very similar to other results already obtained in the literature.The novelty lies on the fact that we derive our assertions in general Banach spaces, and avoid the use of the Asplund assumption.
