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…
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…
Limit Points for Browder Spectrum of Operator Matrices
Abdelaziz Tajmouati, Mohammed Karmouni, Safae Alaoui Chrifi
Let and , where and are Banach spaces, and let be an operator acting on given by $M_C=\begin{pmatrix} A & C \…
Quasi-Fredholm, Saphar Spectra for Integrated Semigroup
Abdelaziz Tajmouati, Hamid Boua, Mohamed Karmouni
In this paper, we show a spectral inclusion of integrated semigroups for Saphar, essentially Saphar and quasi-Fredholm spectra.
Semi-Fredholm and semi-Browder spectrums for the -times integrated semigroups
Abdelaziz Tajmouati, Abdeslam El Bakkali, Mohamed Baba Mohamed Ahmed +1
In this paper, we describe the different spectrums of the α-times integrated semigroups by the spectrums of their generators. Specially, essential ascent and descent, upper and low…
