Existence of pseudo-relative sharp minimizers in set-valued optimization. (English) Zbl 1478.90115

Appl. Math. Optim. 84, No. 3, 2969-2984 (2021); correction ibid. 90, No. 1, Paper No. 8, 2 p. (2024).
Summary: In this paper, we propose new concepts of sharp minimality in set-valued optimization problems by means of the pseudo-relative interior, namely pseudo-relative \(\phi \)-sharp minimizers. Based on this notion of minimality, we extend the existence result of a unique minimum of uniformly convex real-valued functions proved by C. Zălinescu [Convex analysis in general vector spaces. Singapore: World Scientific (2002; Zbl 1023.46003)] to vector-valued as well as set-valued maps. Additionally, we provide some existence results for weak sharp minimizers in the sense of M. Durea and R. Strugariu [Nonlinear Anal., Theory Methods Appl., Ser. A, Theory Methods 73, No. 7, 2148–2157 (2010; Zbl 1225.90115)].
