Abstract

In this paper, the concepts of deferred conullity for an FK-space X containing φ1, and deferred wedgeness are defined. We also define deferred semi-conservative FK-space and give its relation to these concepts. The other hand, we have examined their relationship to ordinary conullity and Cesaro conullity. Furthermore, we have defined the deferred distinguished subspaces DpqW, DpqS, DpqF of an FK-space X. Also, we obtain some results for a summability domain YA to be deferred conull FK-space.
