摘要：
In this paper, we study the behavior of some topological and cardinal properties of topological spaces under the influence of the N-tau(phi)-kernel of a space X. It has been proved that the N-tau(phi)-kernel of a space X preserves the density and the network ir- weight of normal spaces. Besides, shown that the N-compact kernel of a space X preserves the Souslin properties, the weight, the density, and the ir-network weight of normal spaces.
