Compressible Matrix Algebras and the Distance from Projections to Nilpotents
(University of Waterloo, 20191115)In this thesis we address two problems from the fields of operator algebras and operator theory. In our first problem, we seek to obtain a description of the unital subalgebras $\mathcal{A}$ of $\mathbb{M}_n(\mathbb{C})$ ... 
Exact C*algebras and the KirchbergPhillips Nuclear Embedding Theorem
(University of Waterloo, 20190808)A C*algebra A is exact if the functor A ⊗ min (·) preserves short exact sequences. This is equivalent to the algebra A having a nuclear faithful *representation. Exact C*algebras are a class of C*algebras which is ... 
Graph C*algebras and the Abelian Core
(University of Waterloo, 20160826)We may associate to a C*algebra to the directed graph E by associating edges to partial isometries and vertices to pairwise orthogonal Hilbert spaces which satisfy some additional conditions. Such graph algebras were first ...
