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…

Approximate diagonalization of self--adjoint matrices over

Yifeng Xue

Let be a compact Hausdorff space. We prove that in this paper, every self--adjoint matrix over is approximately diagonalizable iff and $\HO^2(M,\mathbb Z)\…

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…
