Convexity and Freezing Sets in Digital Topology
Published 19 May 2020 in math.GT | (2005.09713v1)
Abstract: We continue the study of freezing sets in digital topology, introduced in [2]. We show how to find a minimal freezing set for a "thick" convex disk X in the digital plane Z2. We give examples showing the significance of the assumption that X is convex.
