ON PREUSS CONNECTEDNESS CONCEPT IN FTS

The principal aim of this paper is to examine the extent to which certain connectedness concepts in FFS can be viewed as connectedness in Preuss' sense i.e., as subclasses of absolute value of FTS which equal CE: = {X is-an-element-of absolute value of FTS \ f is-an-element-of FTS(X, Y), Y is-a-element-of E double-line arrow pointing right f is constant), for some E subset-of absolute value of FTS. Two new connectedness concepts in FTS, which subsume an existing concept, are shown capable of being so viewed while it turns out that certain existing, otherwise good, connectedness concepts cannot be so viewed.
