On the spectrum of stochastic perturbations of the shift and Julia sets
(Polish Acad Sciences Inst Mathematics, 2012-01-01)
We extend the Killeen-Taylor study [Nonlinearity 13 (2000)] by investigating in different Banach spaces (l(alpha)(N), c(0)(N),c(N)) the point, continuous and residual spectra of stochastic perturbations of the shift operator ...

Linear combinations of frame generators in systems of translates
(Elsevier Inc, 2013-12)
A finitely generated shift invariant space V is a closed subspace of L2(Rd) that can be generated by the integer translates of a finite number of functions. A set of frame generators for V is a set of functions whose integer ...
Dynamical sampling for shift-preserving operators
(Academic Press Inc Elsevier Science, 2021-03)
In this note, we solve the dynamical sampling problem for a class of shift-preserving operators L:V→V acting on a finitely generated shift-invariant space V. We find conditions on L and a finite set of functions of V so ...
Blur shift spaces: a multi-point compactification scheme for infinite-alphabet shift spaces
(2021)
Propomos um novo tipo de espaços shift, chamados blur shift spaces. Estes espaços são construídos a partir de espaços shift clássicos, aumentando-se o alfabeto com símbolos que representam subconjuntos infinitos do alfabeto ...
Preliminary results concerning the VSS X- chart with unknow in-control parameters
(2010-12-01)
The VSS X- chart is known to perform better than the traditional X- control chart in detecting small to moderate mean shifts in the process. Many researchers have used this chart in order to detect a process mean shift ...

Classification of sofic projective subdynamics of multidimensional shifts of finite type
(Amer Mathematical Soc, 2015)
Motivated by Hochman's notion of subdynamics of a Z(d) subshift (2009), we define and examine the projective subdynamics of Z(d) shifts of finite type (SFTs) where we restrict not only the action but also the phase space. ...
