Contribution
It defines and studies C*-algebras over topological spaces and introduces an analogue of the bootstrap class for finite spaces, expanding the theoretical framework.
Findings

Definition of bootstrap class for C*-algebras over finite spaces
Insights into non-Hausdorff topological space cases
Abstract
We carefully define and study C*-algebras over topological spaces, possibly non-Hausdorff, and review some relevant results from point-set topology along the way. We explain the triangulated category structure on the bivariant Kasparov theory over a topological space. We introduce and describe an analogue of the bootstrap class for C*-algebras over a finite topological space.
