Abstract

In this paper, we give a topological version of Scott convergence theorem for locally hypercompact spaces. We introduce the notion of SX\mathcal{S}^*_X-convergence on a T0T_0 topological space XX, and define the notion of finitely approximated spaces. Monotone determined spaces are natural topological extensions of dcpos. The main results are: (1) A monotone determined space XX is a locally hypercompact space iff SX\mathcal{S}^*_X-convergence is topological. (2) For a T0T_0 space XX, SX\mathcal{S}^*_X-convergence is topological iff XX is a finitely approximating space. (3) If the Lawson topology on a monotone determined space XX is compact, then XX is a dcpo endowed with the Scott topology.
