Fixed point on a graph
WebFeb 1, 2015 · In this paper, we prove fixed point results for set-valued maps, defined on the family of closed and bounded subsets of a metric space endowed with a graph and satisfying graph ϕ -contractive conditions. These results extend and strengthen various known results in [ 7, 8, 11, 19 – 21 ].

Consider a directed graph G such that the set of its vertices coincides with X ( i.e., MathML) and the set of its edges MathML. We assume that G has no parallel edges and weighted graph by assigning to each edge the distance between the vertices; for details about definitions in graph theory, see [ 18 ].

Not all functions have fixed points: for example, f(x) = x + 1, has no fixed points, since x is never equal to x + 1 for any real number. In graphical terms, a fixed point x means the point (x, f(x)) is on the line y = x, or in other words the graph of f has a point in common with that line..
