The aim of this paper to introduce the concept of α̂g-kernel also we introduced the concept of the weakly ultra α̂g-separation of two sets in a topological space using α̂g-open sets. The α̂g-closure is defined in terms of this weakly ultra α̂g-separation. We also investigate some properties of weak separation axioms like α̂g-Ri-spaces, i = 0,1 and α̂g-Ti-spaces, i = 0,1,2.
