Lefschetz fixed point theorem for digital images
Özgür Ege, İsmet Karaca · Fixed Point Theory and Applications · 2013
In this article we study the fixed point properties of digital images. Moreover, we prove the Lefschetz fixed point theorem for a digital image. We then give some examples about the fixed point property. We conclude that sphere-like digital images have the fixed point property. MSC: 55N35, 68R10, 68U05, 68U10.
