The K-Theory of Toeplitz C*-Algebras of Right-Angled Artin Groups
Nikolay A. Ivanov
To a graph one can associate a C^*-algebra generated by isometries. Such -algebras were studied recently by Crisp and Laca. They are a special case of the Toeplit…

On the Structure of Some Reduced Amalgamated Free Product C*-Algebras
Nikolay A. Ivanov
We study some reduced free products of C*-algebras with amalgamations. We give sufficient conditions for the positive cone of the K_0 group to be the largest possible. We also give…

Reduced Free Products of Finite Dimensional -Algebras
Nikolay A Ivanov
We find a necessary and sufficient conditions for the simplicity and uniqueness of trace for reduced free products of finite families of finite dimensional -algebras with spec…
