Ideals and Maximal Commutative Subrings of Graded Rings
… investigation originates in the theory of C*-crossed product algebras associated to topological dynamical systems, where connections between intersection properties of ideals and maximal commutativity of certain subalgebras are well-known. In the last few years, algebraic analogues of these …

Tracial Rokhlin Property and Non-Commutative Dimensions
… property and the structure of the corresponding crossed products. It consists of two major parts. For the first part, we study several different aspects of finite group actions with certain versions of the Rokhlin property. We are able to give an explicit characterization of product-type actions …

On decompositions and Connes's embedding problem of finite von Neumann algebras
… mappings, conditional expectations, tensor products, crossed products, direct integrals, and Jones basic construction.</p><p>Chapter 2 introduces new decompositions of finite von Neumann algebras which we call F-thin, strongly F-thin, and weakly F-thin, etc. We also consider the …

Structure of Intermediate C*-subalgebras of discrete group actions
… thcal{B}\subseteq\mathcal{A}\rtimes_r\Gamma$ is a crossed product. We show that for a large class of actions $\Gamma\curvearrowright\mathcal{A}$ of $C^*$-simple groups $\Gamma$ on unital $C^*$-algebras $\mathcal{A}$, including any non-faithful action of a hyperbolic group with trivial amenable …

Non commutative version of arithmetic geometric mean inequality and crossed product of ternary ring of operators
… of Zettl's decomposition theorem, we introduce crossed products of ternary ring of operators (the full crossed product and the reduced crossed product). We also prove that $V\rtimes_{\alpha^{V}}G$ as the off-diagonal corner of the $C^*$-algebra $A(V)\rtimes_{\alpha^{A(V)}}G$. Equivalently, we …
