| Title: | Dimension theories for C*-algebras |
| Seminar: | Department of Mathematics Colloquium |
| Speaker: | Andrew Toms, York University, Toronto |
| Abstract: |
| The study of C*-algebras may be regarded as noncommutative topology. As such, is it natural to ask for C*-algebra generalisations of notions from the study of locally compact Hausdorff spaces. One such notion is the covering dimension of the space. In this talk I will survey various methods of generalising this concept to C*-algebras, and also variants on these methods which account more effectively for the "matricial" structure of C*-algebras. We will define dimensions for C*-algebras by topological, operator algebraic, and homological means, and see how they are sensitive to differences between steadily more exotic C*-algebras. Finally, we will discuss the relationships between these dimension theories, and their bearing on K-theoretic rigidity phenomena. |
