COUNTEREXAMPLES IN CHAOTIC GENERALIZED SHIFTS
In the following text for arbitrary $X$ with at least two elements, nonempty countable set $Gamma$ we make a comparative study on the collection of generalized shift dynamical systems like $(X^Gamma,sigma_varphi)$ where $varphi:GammatoGamma$ is an arbitrary self-map. We pay attention to sub-systems and combinations of generalized shifts with counterexamples regarding Devaney, exact Dev...
متن کاملCued shifts of attention and memory encoding in partial report: a dual-task approach.
This study explores how cued shifts of visual attention and rapid encoding of visual information relate to limited-capacity processing mechanisms. Three experiments were conducted placing a partial-report task within a dual-task paradigm. Experiments 1 and 2 involved a simple speeded visual discrimination (Task 1) and then an unspeeded partial-report task (Task 2). Generally, Task 2 accuracy de...
متن کاملPartial sums and optimal shifts in shifted large−l perturbation expansions for quasi-exact potentials
For the N−plets of bound states in a quasi-exactly solvable (QES) toy model (sextic oscillator), the spectrum is known to be given as eigenvalues of an N by N matrix. Its determination becomes purely numerical for all the larger N > N0 = 9. We propose a new perturbative alternative to this construction. It is based on the fact that at any N , the problem turns solvable in the limit of very larg...
متن کاملAlmost specification and renewality in spacing shifts
Let $(Sigma_P,sigma_P)$ be the space of a spacing shifts where $Psubset mathbb{N}_0=mathbb{N}cup{0}$ and $Sigma_P={sin{0,1}^{mathbb{N}_0}: s_i=s_j=1 mbox{ if } |i-j|in P cup{0}}$ and $sigma_P$ the shift map. We will show that $Sigma_P$ is mixing if and only if it has almost specification property with at least two periodic points. Moreover, we show that if $h(sigma_P)=0$, then $Sigma_...
