Abstract

The concepts of Δ-convergence and ΔL-convergence of a net are introduced in Δ-space defined by Zhang et.al. The characterization of the continuity of the Δ-space is obtained in terms of the Δ-convergence of the nets. The result that the continuity of the Δ-space implies the ΔL-convergence being topological in Δ-space is given. An example is supplied to illustrate that the converse of the above result does not hold. Meantime, we prove that the Δ-space X is continuous if and only if the ΔL-convergence is topological in X, X is meet-continuous and  O ( X ) ω ( X ) = τ Δ L . Moreover, we put forward the concept of weak continuity of the Δ-space and show that a sufficient and necessary condition for the Δ-space being weak continuous is that the ΔL-convergence is topological.
