For ? > 0 and a bounded linear operator T acting on some Hilbert space, the ?-pseudospectrum of T is ??(T) = {z ? C : ||(zI-T)-1|| > ?-1}. This note provides a characterization of those operators T satisfying ??(T) = ?(T) + B(0,?) for all ? > 0. Here

This paper discusses the stability of a kind of spectral property called property (R) under compact perturbations in the setting of Hilbert space. Necessary and sufficient conditions are given for such a spectral property to be invariant under compac

In this paper, we introduce an integer-valued threshold autoregressive process, which is driven by independent negative-binomial distributed random variables and based on negative binomial thinning. Basic probabilistic and statistical properties of t

For $\varepsilon\gt 0$ and a bounded linear operator $T$ acting on some Hilbert space, the $\varepsilon$ -pseudospectrum of $T$ is $\sigma_{\varepsilon}(T)=\{z\in\mathbb{C}:\|(zI-T)^{-1}\|\gt 1/\varepsilon\}$ and the $\varepsilon$ -pseudospectral rad

The aim of this paper is to explore the stability of several Weyl type theorems (including Weyl’s theorem, a-Weyl’s theorem, Browder’s theorem and a-Browder’s theorem) under compact perturbations in the setting of Hilbert space. It is complet

In this paper, we propose several approaches to estimate the parameters of the periodic first-order integer-valued autoregressive process with period T (PINAR(1)T) in the presence of missing data. By using incomplete data, we propose two approaches t
