We show that the homology digraph is a directed homotopy invariant and establish variants of the main results of ordinary singular homology theory for the homology digraph. In particular, we prove a Künneth formula, which enables one to compute the homology digraph of a product of preordered ...
HOMOTOPY theoryCOINCIDENCE theoryMETRIC spacesCOINCIDENCEThe basic purpose of this article is to introduce the concept of R-纬-G-contraction by using R-functions, lower semi-continuous functions and digraphs and discuss the existence and uniqueness of points of coincidence and common fixed ...
