Finite Generation of Ext-Algebras of Finite Dimensional Algebras and Associated Monomial Algebras
<p>In this thesis, we investigate the Ext-algebra of a basic, finite dimensional $K$-algebra $A=K\mathcal{Q}/I$, where $K$ is an algebraically closed field and $\mathcal{Q}$ is a finite quiver. We denote the Ext-algebra of $A$ by $E(A)$. We denote $\bar{A}=A/A^+$ to be the direct sum of all simple …

Approximating rotation algebras and inclusions of C*-algebras
… of this thesis is the approximation of rotation algebras in the quantum Gromov–Hausdorff distance. We introduce the completely bounded quantum Gromov–Hausdorff distance and show that for even dimensions, the higher dimensional rotation algebras can be approximated by matrix algebras in this …

Finite Generation of Ext-Algebras for Monomial Algebras
… generation of the cohomology rings of monomial algebras, and thereafter G. Davis determined a finite criteria for such generation in the case of cycle algebras. Herein, we describe the construction of a finite directed graph upon which criteria can be established to determine finite generation …

On Schur algebras, Doty coalgebras and quasi-hereditary algebras
Motivated by Doty's Conjecture we study the coalgebras formed from the coefficient spaces of the truncated modules. We call these the Doty Coalgebras D_(n,p)(r). We prove that D_(n,p)(r) = A(n,r) for n = 2, and also that D_(n,p)(r) = A(\pi,r) with \pi a suitable saturated set, for the cases; i) n = …

Kadison -Singer algebras with applications to von Neumann algebras
<p>I develop the theory of Kadison-Singer algebras, introduced recently by Ge and Yuan. I prove basic structure theorems, construct several new examples and explore connections to other areas of operator algebras. In chapter 1, I survey those aspects of the theory of non-selfadjoint algebras that …

On Morita Equivalences Between KLR Algebras and VV Algebras
… properties of a recently de�ned family of graded algebras, which we call VV algebras. These algebras were de�ned by Varagnolo and Vasserot. We compare categories of modules over KLR algebras with categories of modules over VV algebras, establishing various Morita equivalences. Using these Morita …

Unitary representations of rational Cherednik algebras and Hecke algebras
… the lowest weight category of rational Cherednik algebras of complex reflection groups. We provide the complete classification of unitary representations for the symmetric group, the dihedral group, as well as some additional partial results. We also study the unitary representations of Hecke …

Ideals in von Neumann algebras and in associated operator algebras
… admit certain generalisations to van Neumann algebras. One of the characterisations of the ideal of compact operators is that it is the closure of the ideal of finite rank operators, and hence the closed ideal generated by the finite dimensional projections. Kaftal has considered the ideal of …

Kadison -Singer algebras
