Noncommutative Spherical Tight Frames in finitely generated Hilbert C*-modules
Do Ngoc Diep
In the paper we describe the C*-algebras of noncommutative spherical tight frames over some C*-algebras and then apply to study the noncommutative version of the universal classify…

-graded Cech Cohomology in Noncommutative Geometry
Do Ngoc Diep
The Z_2-graded Cech cohomology theory is considered in the framework of noncommutative geometry over complex number field and in particular the homotopy invariance and Morita invar…

On the Structure of Lie Group C*-Algebras and Compact Quantum Groups
Do Ngoc Diep
We expose a K-theoretic approach to study group C*-algebras and C*-algebraic compact quantum groups: 1. The conception of multidimensional geometric quantization and the index of g…
