Property (gb) through local spectral theory [PDF]
, 2014 Property (gb) for a bounded linear operator T on a Banach space X means that the points c of the approximate point spectrum for which c I-T is upper semi B-Weyl are exactly the poles of the resolvent. In this paper we shall give several characterizations

The spectrum of the Laplacian on closed manifolds and the heat asymptotics near cones
, 2023 Let $\mathcal{M}$ be a smooth, closed and connected manifold of dimension $n\in\mathbb{N}$, endowed with a Riemannian metric $g$. Moreover, let $\mathcal{B}$ be an $(n+1)$-dimensional compact manifold with boundary equal to $\mathcal{M}$. Endow $\mathcal{

Local spectral radius formulas for a class of unbounded operators on Banach spaces
, 2011 We exhibit a general class of unbounded operators in Banach spaces which can be shown to have the single-valued extension property, and for which the local spectrum at suitable points can be determined. We show that a local spectral radius formula holds,

Real Paley-Wiener theorems and local spectral radius formulas
, 2009 We systematically develop real Paley-Wiener theory for the Fourier transform on R^d for Schwartz functions, L^p-functions and distributions, in an elementary treatment based on the inversion theorem.

Notas sobre propiedades espectrales de un operador, su heredabilidad y aplicaciones [PDF]
, 2019 In this paper we describe the behavior of Weyl type theorems or Weyl type properties, for an operator $T$ on a proper closed and $T$-invariant subspace $W\subseteq X$ such that $T^n(X)\subseteq W$, for some $n\geq 1$, where $T\in L(X)$ and $X$ is an ...
