We investigate the subject of linear dynamics by studying the notion of frequent hypercyclicity for bounded operators T on separable complex F-spaces: T is frequently hypercyclic if there exists a vector x such that for every nonempty open subset U of X, the set of integers n such that Tnx belongs to U has positive lower density. We give several criteria… (More)

This study extends an examination of the behavioral and pituitary-adrenal responses of infant squirrel monkeys (Saimiri sciureus) separated from their mothers under different environmental conditions to another physiological system by measuring the metabolites of the central monoamines found in the cerebrospinal fluid (CSF). This study included… (More)

We study boundary properties of universal Taylor series. We prove that if f is a universal Taylor series on the open unit disk, then there exists a residual subset G of the unit circle such that f is unbounded on all radii with endpoints in G. We also study the effect of summability methods on universal Taylor series. In particular, we show that a Taylor… (More)

The effects of maternal proximity on the behavioral and physiological responses of infant rhesus macaques during 4 days of total or adjacent separations from the mother were studied. The 6 infants tested showed behavioral responses that differentiated the two separation conditions. Major differences were found in the quantity and quality of vocalizations,… (More)

This study examined reactions to mirror-image stimulation in a wild- reared adult male monkey (Macaca tonkeana) which had spontaneously developed a form of tool-use, namely the use of plant stems to reach mucus inside the nose. Initial intense social responsiveness to the mirror was followed by habituation, although some social responding persisted. Mirror-… (More)

Scientific inquiry, for the most part, can be described as parochial. Not only are there clear demarcations between broad disciplinary categories (i.e., anatomy, physiology, psychology), but subspecialties are common within disciplines. Modern technology has made possible a trend toward greater and greater specialization. In fact, there are now areas of… (More)

We show that the set of continuous nowhere differentiable functions, the set of Dirichlet series which are bounded in the right half-plane and diverge everywhere on the imaginary axis, and the set of continuous interpolating functions contain big algebras. Mathematics Subject Classification: 46B25, 46E25.

We solve several problems on frequently hypercyclic operators. Firstly, we characterize frequently hypercyclic weighted shifts on l(Z), p ≥ 1. Our method uses properties of the difference set of a set with positive upper density. Secondly, we show that there exists an operator which is U-frequently hypercyclic, yet not frequently hypercyclic and that there… (More)

When these two dimensions coincide, we say that μ admits a local dimension at x and we denote this common value dimloc(μ;x). The study of pointwise dimension maps and their relationship to Hausdorff dimension goes back to Bilingsley ([Bil60], [Bil61]). Setting E−(μ;α) = {x ∈ K; dimloc(μ;x) ≤ α} E(μ;α) = {x ∈ K; dimloc(μ;x) ≤ α}, it is well known that… (More)
