Semi-browder Essential Spectra of Quasisimilar Operators
نویسندگان
چکیده
If T and S are quasisimilar bounded operators on Banach spaces, we prove that each closed-and-open subset of the lower semiBrowder essential spectrum of T intersects one special part of the upper semi-Browder essential spectra of T and S. AMS Mathematics Subject Classification (1991): 47A53, 47A10

Stability of essential spectra of bounded linear operators
In this paper, we show the stability of Gustafson, Weidmann, Kato, Wolf, Schechter and Browder essential spectrum of bounded linear operators on Banach spaces which remain invariant under additive perturbations belonging to a broad classes of operators $U$ such $gamma(U^m)
متن کاملPerturbation Results on Semi-Fredholm Operators and Applications
We give some results concerning stability in the Fredholm operators and Browder operators set, via the concept of measure of noncompactness. Moreover, we prove some localization results on the essential spectra of bounded operators on Banach space. As application, we describe the essential spectra of weighted shift operators. Finally, we describe the spectra of polynomially compact operators, a...
متن کاملOn the semi-Browder spectrum
An operator in a Banach space is called upper (lower) semi-Browder if it is upper (lower) semi-Fredholm and has a finite ascent (descent). We extend this notion to n-tuples of commuting operators and show that this notion defines a joint spectrum. Further we study relations between semi-Browder and (essentially) semiregular operators. Denote by L(X) the algebra of all bounded linear operators i...
متن کاملWeyl ’ S Theorem and Tensor Products : a Counterexample Derek Kitson ,
Approximately fifty percent of Weyl’s theorem fails to transfer from Hilbert space operators to their tensor product. As a biproduct we find that the product of circles in the complex plane is a limaçon. 0. Introduction To say that “Weyl’s theorem holds”, for a bounded operator T ∈ B(X) on a Banach space X , is to assert [2],[4],[5] that 0.1 σ(T ) \ ωess(T ) = π 00 (T ) ≡ iso σ(T )∩π 0 (T ) : t...
متن کاملEigenvalue Estimates in the Semi-classical Limit for Pauli and Dirac Operators with a Magnetic Field
Leading order semi-classical asymptotics are given for the distribution of the eigen-values of Dirac and Pauli operators describing an electron in an electromagnetic eld. Minimal conditions are assumed on the electric and magnetic potentials to ensure the existence of only a nite number of eigenvalues outside the essential spectra. The method used is based on coherent state analysis.
