The Ext--Group of Unitary Equivalence Classes of Unital Extensions
Yifeng Xue
Let $\A$ be a unital separable nuclear --algebra which belongs to the bootstrap category and $\B$ be a separable stable --algebra. In this paper, we consider the gro…
Nonstable --theory for extension algebras of the simple purely infinite --algebra by certain --algebras
Zhihua Li, Yifeng Xue
Let $0\longrightarrow \B\stackrel{j}{\longrightarrow}E\stackrelπ{\longrightarrow}\A\longrightarrow 0$ be an extension of $\A$ by $\B$, where $\A$ is a unital simple purely infinite…
Relatively spectral homomorphisms and K-injectivity
Yifeng Xue
Let $\A$ and $\B$ be unital Banach algebras and $ϕ\colon\A\to\B$ be a unital continuous homomorphism. We prove that if is relatively spectral (i.e., there is a dense subalgebra…
Classification of the crossed product for certain pairs
Yifeng Xue
Let be a separable compact Hausdorff space with and be a homeomorphism with prime period (). Set $M_θ=\{x\in M| θ(x)=x\}\not=\varnoth…
