Abstract:

Several recent papers have adapted notions of geometric topology to the emerging field of ‘digital topology.’ An important notion is that of digital homotopy. In this paper, we study a variety of digitally-continuous functions that preserve homotopy types or homotopy-related properties such as the digital fundamental group.

Keywords: digital image; digitally continuous; homeomorphism; retraction; homotopy; fundamental group; digital topology
