报告简介：   

In this talk, I would like to introduce recent works associated with fixed point property and almost fixed point property for digital spaces. The talk will be covered in the following areas: Digital images with digital connectivity; Alexandroff  topological spaces with adjacency; Khalimsky topological spaces with Khalimsky adjacency; Marcus-Wyse topological spaces with Marcus-Wyse adjacency; Kovalevsky's ALF-spaces; SST-topological spaces in Rn; The other Alexandroff topological methods; Order theoretical approach.
