Theoremes ergodiques perturbes

Israel Journal of Mathematics, 1997
We obtain results on almost sure convergence of ergodic averages along arithmetic subsequences perturbed by independent identically distributed random variables having apth finite moment for somep>0. To prove these results, we use methods based on the harmonic analysis and the theory of Gaussian processes.

EXTENDED WEYL TYPE THEOREMS AND PERTURBATIONS

Mathematical Proceedings of the Royal Irish Academy, 2010
Summary: In [\textit{M. Berkani} and \textit{H. Zariouh}, Math. Bohem. 134, No. 4, 369--378 (2009; Zbl 1211.47011)], we introduced the properties \((b)\) and \((gb)\), which are analogous of Browder and generalised Browder theorems. In this paper, we study the stability of properties \((b)\) and \((gb)\) under commutative perturbations by finite rank ...

Weyl’s Theorem and Perturbations

Integral Equations and Operator Theory, 2005
In the present paper we examine the stability of Weyl’s theorem under perturbations. We show that if T is an isoloid operator on a Banach space, that satisfies Weyl’s theorem, and F is a bounded operator that commutes with T and for which there exists a positive integer n such that F n is ...

Perturbation Theorems for Relative Spectral Problems

Canadian Journal of Mathematics, 1972
Eigenvalue problems of the form Af = λBf, where λ is a complex parameter and A and B are operators on a Hilbert Space, have been considered by a number of authors (e.g., [1; 3; 5; 7; 10]). In this paper, we shall be concerned with the existence and nature of eigenfunction expansions associated with such problems, with no assumptions of self-adjointness.

Perturbation theorems for a-times integrated semigroups

Archiv der Mathematik, 2003
Under relative smallness conditions for the perturbing operator \(B\), perturbation results are proved for the generator \((A,D(A))\) of an \(\alpha\)-times integrated semigroup on a Banach space \(X\). More precisely, it is shown that if the estimate \[ \| B(\lambda-A)^{-1}\| \leq M\alpha+1\) if the \(\alpha\)-times integrated semigroup generated by \(
