The plane CS? non-criticality of certain closed sets

Abstract

In this paper we first show that some families of fibers of certain fibrations are neither R-2 nor T-g-CS infinity-critical and then, in the last section, we show that the finite families of disjoint generalized Hawaiian earrings are neither R-2 nor T-g -CS infinity-critical.
