Set-Valued and Variational Analysis, 1994
The author, a leading authority on hyperspaces, provides an excellent survey of Wijsman convergence which was first introduced thirty years back. Originally meant for convex analysis, the convergence was studied in depth by various workers in hyperspaces.

Wijsman convergence of convex sets under renorming
Nonlinear Analysis: Theory, Methods & Applications, 1994Let \((X,\| \cdot\|)\) be a normed space and denote by \(C(X)\) the nonempty closed convex subsets of \(X\). It is known that equivalent norms on \(X\) may determine distinct Wijsman topologies on \(C(X)\). The purpose of the present paper is to describe the weak topology on \(C(X)\) determined by all distance functionals of the form \(d_ p (x,\cdot)\)

λ− Wijsman statistical convergence on time scales
Communications in Statistics - Theory and Methods, 2021We construct λ− Wijsman density and λ− Wijsman statistical convergence (SC) on a time scale. Furthermore, strongly Wijsman λp− summability is defined.

Wijsman regularly ideal invariant convergence of double sequences of sets
2021Summary: In this paper, we introduce the notions of Wijsman regularly invariant convergence types, Wijsman regularly \((\mathcal{I}_{\sigma}, \mathcal{I}^{\sigma}_2)\)-convergence, Wijsman regularly \((\mathcal{I}^*_{\sigma}, \mathcal{I}^{\sigma *}_2)\)-convergence, Wijsman regularly \((\mathcal{I}_{\sigma}, \mathcal{I}^{\sigma}_2)\)-Cauchy double ...

Wijsman lacunary ideal invariant convergence of double sequences of sets
2020Summary: In this paper, we study the concepts of Wijsman lacunary invariant convergence, Wijsman lacunary invariant statistical convergence, Wijsman lacunary \({\mathcal{I}}_2\)-invariant convergence \(({\mathcal{I}}^{{\sigma}{\theta}}_{W_2} )\), Wijsman lacunary \({\mathcal{I}}^\ast_2\)-invariant convergence \(({\mathcal{I}}^{\ast} {}^{{\sigma}{\theta}

Wijsman convergence in the hyperspace of a metric space
1985Let (X,d) be a metric space with metric d. This paper studies Wijsman convergence (w-convergence for short) in 2 x, the power set of X, and \(2_ 0\) X the subfamily of non-empty subsets of X, as well as the hyperspace c(X), which is the set of all closed subsets of X and \(C_ 0(X)\) the set of all non-empty closed subsets of X.
