Local Ergodic Theorems for C0-Semigroups
Abdelaziz Tajmouati, Fatih Barki
Let be a -semigroup of bounded linear operators on the Banach space into itself and let be their infinitesimal generator. In this paper, we show…
Generalized Drazin-Riesz Invertibility for Operators Matrices
Abdelaziz Tajmouati, Mohammed Karmouni, Safae Alaoui Chrifi
Let , and where and are infinite Banach or Hilbert spaces. Let $M_{C}=\begin{pmatrix} A & C\cr 0 & B \end{pm…
Semi-Fredholm and Semi-Browder Spectra For -Quasi-Semigroups
Abdelaziz Tajmouati, Youness Zahouan
In this paper, we describe the different spectra of the -quasi-semigroups by the spectra of their generators. Specially, essential ascent and descent,Drazin invertible, upper…
On Orbit Reflexive Tuple of Operators And Weak Orbit Reflexivity
Abdelaziz Tajmouati, Youness Zahouan
In this paper we give a various conditions for which the tuple of commutative bounded linear operators on an infinite dimensional ( re…
Spectral Inclusions Between C0-Quasi-Semigroups and Their Generators
Abdelaziz Tajmouati, Youness Zahouan, Mohamed Ahmed Ould Mohamed Baba
In this paper, we show a spectral inclusion of a different spectra of a C0-quasi-semigroup and its generator and precisely for ordinary, point, approximate point, residual, essenti…
Cesàro-Hypercyclic and Weyl type theorem
Abdelaziz Tajmouati, Mohammed El Berrag
In this paper we study the relations between Cesàro-hypercyclic operators and the operators for which Weyl type theorem holds.
