Abstract  

We consider Hausdorff operators generated by a function ϕ integrable in Lebesgue"s sense on either R or R 2, and acting on the real Hardy space H 1(R), or the product Hardy space H 11(R R), or one of the hybrid Hardy spaces H 10(R 2) and H 01(R 2), respectively. We give a necessary and sufficient condition in terms of ϕ that the Hausdorff operator generated by it commutes with the corresponding Hilbert transform.

Abstract  

A bibliometric analysis of Spanish cardiovascular research is presented. The study focuses on the productivity, visibility and citation impact in an international, notably European context. Special attention is given to international collaboration. The underlying bibliographic data are collected from Thomson Reuters’s Web of Science on the basis of a ‘hybrid’ search strategy combining core journals, lexical terms and citation links especially developed for the field of cardiology.

Abstract  

In this paper, we will study the field through the problematic network built by scientific articles, using actor-network theory (and consequently coword analysis) as a model for scientific knowledge (regarded as a social process) growth. Scientometrics is an hybrid field made of invisible college and a lot of users, thus controlled by both scientific research and final uses. Coword analysis gives the same weight to all articles, cited or not, and consequently computes the interaction network within all kind of authors. According to already described network properties of scientific interaction, coword analysis describes the dynamic of the field in accordance with what has been observed, and suggest forecast for the future.

Summary In the present study full-text analysis and traditional bibliometric methods are combined to improve the efficiency of the individual methods in the mapping of science. The methodology is applied to map research papers from a special issue of Scientometrics. The outcomes substantiate that such hybrid methodology can be applied to both research evaluation and information retrieval. The subject classification given by the guest-editors of the special issue is used for validation purposes. Because of the limited number of papers underlying the study the paper is considered a pilot study that will be extended in a later study on the basis of a larger corpus.

Abstract  

It is shown that the maximal operator of the one-dimensional dyadic derivative of the dyadic integral is bounded from the dyadic Hardy-Lorentz spaceH p,q toL p,q (1/2<p<∞, 0<q≤∞) and is of weak type (L 1,L 1). We define the twodimensional dyadic hybrid Hardy spaceH 1 and verify that the corresponding maximal operator of a two-dimensional function is of weak type (H 1 ,L 1). As a consequence, we obtain that the dyadic integral of a two-dimensional functionfεH 1 LlogL is dyadically differentiable and its derivative is a.e.f.
