On convergence in the space of closed subsets of a metric space
E. A. Panasenko Tambov State University named after G.R. Derzhavin
Abstract:
We consider the space
clos(X) of closed subsets of unbounded (not necessarily
separable) metric space (X,ϱX) endowed with the metric
ρclX introduced in [Zhukovskiy E.S., Panasenko E.A. //
Fixed Point Theory and Applications. 2013:10]. It is shown that if any closed
ball in the space (X,ϱX) is totaly bounded, then convergence in the space
(clos(X),ρclX) of a sequence {Fi}∞i=1 to F is equivalent to convergence in the sense of
Wijsman, that is to convergence for each x∈X of the distances
ϱX(x,Fi) to ϱX(x,F).
Keywords:
space of closed subsets of a metric space, Wijsman convergence, metrizability.
