On locally finite-dimensional traces II
Mehdi Moradi, Massoud Amini
We continue the study of locally finite-dimensional traces introduced in our earlier work. We give new characterizations of LFD traces in terms of finite-rank projections in irredu…
Equivariant (co)module nuclearity of -crossed products
Massoud Amini, Qing Meng
We define an equivariant and equicovariant versions of the notion of module nuclearity. More precisely, for a discrete group and operator --(co)module $\mathcal…
Cuntz-Nica-Pimsner algebras of product systems over groupoids
Massoud Amini, Mahdi Moosazadeh
Let be a product system over a quasi-lattice ordered groupoid . Under mild hypotheses, we associate to a -algebra which is couniversal for injective Nica covari…
On simplicity of Cuntz algebra and its generalizations
Massoud Amini, Mahdi Moosazadeh
Cuntz algebra is the universal -algebra generated by two isometries satisfying . This is separable, simple, infinite -algeb…
