The Many Faces of Topology

[fresh_42]

Topology as a branch of mathematics is a bracket that encompasses many different parts of mathematics. It is sometimes even difficult to see what all these branches have to do with each other or why they are all called topology. This article aims to shed light on this question and briefly summarize the content of the many branches of topology. We start with a historical review and move from pure set topology through the various analytical and geometric aspects of topology to algebraic varieties and buildings with apartments of Coxeter complexes and Weyl chambers. It should be noted that the transitions between some sub-areas such as topological analysis and differential topology or differential topology and algebraic topology or combinatorial and geometric topology are often fluid, and the categorization made here can only be fundamental.
