States on sharply dominating effect algebras
Zdenka Riecanova, Wu Junde
We prove that Archimedean sharply dominating atomic lattice effect algebras can be characterized by property called basic decomposition of elements. As an application we prove the…
Demi-linear Analysis II -- Demi-distributions
Ronglu Li, Shuhui Zhong, Dohan Kim +1
In this paper, we establish a demi-distributions theory which develops the usual distribution theory, in particular, we show that many conclusions as differentiations, Fourier tran…
Demi-linear Analysis III -- Demi-distributions with Compact Support
Ronglu Li, Shuhui Zhong, Dohan Kim +1
A series of detailed quantitative results is established for the family of demi-distributions which is a large extension of the family of usual distributions.
Samuel multiplicities and Browder Spectrum of Operator Matrices
Shifang Zhang, Junde Wu
we show that the definitions of some classes of semi-Fredholm operators, which use the language of algebra and first introduced by X. Fang in [8], are equivalent to that of some we…
Fredholm Perturbation of Spectra of Upper Triangular Matrix
Zhang Shifang, Zhong Huaijie, Wu Junde
As we knew, study the perturbation theory of spectra of operator is a very important project in mathematics physics, in particular, in quantum mechanics. In this paper, we characte…
Spectra of Upper-triangular Operator Matrix
Zhang Shifang, Zhong Huaijie, Wu Junde
Let and be Banach spaces, , , , $M_{C}=({cc}A&C 0&B)$ be the operator matrix acting on the Banach space . In this paper, we g…
