“An Introduction to Cohomology of Small Categories”
Abstract: In this talk, we will explore various definitions of the cohomology of (small) categories, depending upon the coefficient system, such as traditional category cohomology (1965), Buaes-Wirsching Cohomology (1985), and Thomason Cohomology (2013). After introducing fundamental concepts and frameworks, we give a detailed examination of cohomology computations for simple examples of categories. Lastly, we will finish by introducing the functoriality problem. This presentation is aimed at an audience ranging from undergraduates to researchers, and no prior knowledge is necessary.
