Weyl’s Theorem for Algebraically Paranormal Operators
Let T be an algebraically paranormal operator acting on Hilbert space. We prove : (i) Weyl’s theorem holds for f(T ) for every f ∈ H(σ(T )); (ii) a-Browder’s theorem holds for f(S) for every S ≺ T and f ∈ H(σ(S)); (iii) the spectral mapping theorem holds for the Weyl spectrum of T and for the essential approximate point spectrum of T .

متن کاملWEYL’S THEOREM FOR ALGEBRAICALLY k-QUASICLASS A OPERATORS
If T or T ∗ is an algebraically k-quasiclass A operator acting on an infinite dimensional separable Hilbert space and F is an operator commuting with T , and there exists a positive integer n such that F has a finite rank, then we prove that Weyl’s theorem holds for f(T )+F for every f ∈ H(σ(T )), where H(σ(T )) denotes the set of all analytic functions in a neighborhood of σ(T ). Moreover, if ...
متن کاملFUGLEDE-PUTNAM THEOREM FOR w-HYPONORMAL OR CLASS Y OPERATORS
An asymmetric Fuglede-Putnam’s Theorem for w−hyponormal operators and class Y operators is proved, as a consequence of this result, we obtain that the range of the generalized derivation induced by the above classes of operators is orthogonal to its kernel.
متن کاملPROPERTY (ω) AND QUASI-CLASS (A,k) OPERATORS
In this paper, we prove the following assertions: (i) If T is of quasiclass (A, k), then T is polaroid and reguloid; (ii) If T or T ∗ is an algebraically of quasi-class (A, k) operator, then Weyls theorem holds for f(T ) for every f ∈ Hol(σ(T )); (iii) If T ∗ is an algebraically of quasi-class (A, k) operator, then a-Weyls theorem holds for f(T ) for every f ∈ Hol(σ(T )); (iv) If T ∗ is algebra...
متن کاملEvans Function for Lax Operators with Algebraically Decaying Potentials
We study the instability of algebraic solitons for integrable nonlinear equations in one spatial dimension that include modified KdV, focusing NLS, derivative NLS, and massive Thirring equations. We develop the analysis of the Evans function that defines eigenvalues in the corresponding Lax operators with algebraically decaying potentials. The standard Evans function generically has singulariti...
