Variational Convexity of Functions and Variational Sufficiency in Optimization

open access: yesSIAM Journal on Optimization, 2023
The paper is devoted to the study, characterizations, and applications of variational convexity of functions, the property that has been recently introduced by Rockafellar together with its strong counterpart. First we show that these variational properties of an extended-real-valued function are equivalent to, respectively, the conventional (local ...
