Sandwich type near-rings using some generalized continuities

Recently author(14) constructed sandwich type near-rings using some concepts from modem topology. There are a number of generalizations of continuous maps in the recent developments of topology. It is well known about g-continuity, gc-irresoluteness sg-continuity, pre-sg-continuity and sg-irresoluters in topological spaces. Among these and sg-irresoluteness are the only ones closed under the composition of mappings. In this paper we construct some sandwich type near-rings related to the above classes of mappings with the aid of the modem separation axioms T-1/2 ness and semi-T-1/2 ness. Further, we also obtain two isomorphism theorems for sandwich type near-rings.
