Digital homotopic distance between digital functions




homotopic distance, Lusternik Schnirelmann category, digital topology


In this paper, we define digital homotopic distance and give its relation with LS category of a digital function and of a digital image. Moreover, we introduce some properties of digital homotopic distance such as being digitally homotopy invariance.
