favorite0In section 6 we study universal functions on digital images and their relation to the AFPP.
favorite109In the current paper, we study fixed points and approximate fixed points of digitally continuous functions.
favorite17Among these are several results concerning the relationship between universal functions and the approximate fixed point property (AFPP).
favorite6In the current paper, we obtain additional results concerning fixed points and approximate fixed points of digitally continuous functions.
favorite2Rosenfeld  introduced the notion of a digitally continuous function between digital images, and showed that although digital images need not have fixed point properties analogous to those of the Euclidean spaces modeled by the images, there often are approximate fixed point properties of such images.
