Automorphism group of the open subset inclusion graph of a topological space.

In this paper, we determine automorphisms of j(τ) and prove some results on j(τ),when topological space (X, τ) is finite. Also we determine necessary and sufficient condition for the open subset inclusion graphs of (X, τ1) and (X, τ2) to become isomorphic. Moreover, the topological space (X, τ) whose corresponding open subset inclusion graph is complete, is characterised. [ABSTRACT FROM AUTHOR]
