    Tauberian Korevaar

    No full text
    We focus on the Tauberian work for which Jaap Korevaar is best known, together with its connections with probability theory. We begin (Section 1) with a brief sketch of the field up to Beurling's work. We follow with three sections on Beurling aspects: Beurling slow variation (Section 2); the Beurling Tauberian theorem for which it was developed (Section 3); Riesz means and Beurling moving averages (Section 4). We then give three applications from probability theory: extremes (Section 5), laws of large numbers (Section 6), and large deviations (Section 7). We turn briefly to other areas of Korevaar's work in Section 8. We close with a personal postscript (whence our title).Comment: For the special issue of Indagationes Mathematicae for Jaap Korevaar Centenary, 25.1.202

    Dirichlet forms on metric measure spaces as Mosco limits of Korevaar-Schoen energies

    No full text
    This paper establishes sufficient general conditions for the existence of Mosco limits of Korevaar-Schoen L2L^2 energies, first in the context of Cheeger spaces and then in the context of fractal-like spaces with walk dimension greater than 2. Among the ingredients, a new Rellich-Kondrachov type theorem for Korevaar-Schoen-Sobolev spaces is of independent interest.Comment: Updated versio

    Weak monotonicity property of Korevaar-Schoen norms on nested fractals

    No full text
    In this paper, we study the weak monotonicity property of p-energy related Korevaar-Schoen norms on connected nested fractals for 1<p<1 < p < \infty. Such property has many important applications on fractals and other metric measure spaces, such as constructing p-energies (when p=2p = 2 this is basically a Dirichlet form), generalizing the classical Sobolev type inequalities and the celebrated Bourgain-Brezis-Mironescu convergence.Comment: 10 pages,1 figur

    Going Beyond Counting First Authors in Author Co-citation Analysis

    No full text
    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Dispelling the Myths Behind First-author Citation Counts

    No full text
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods

    Author, publisher and bookseller : a tripartite synergy in Nigerian book industry

    No full text
    This work is about the roles of Author, Publisher and Bookseller in Book development in Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after which it proceeded by defining who an author, a publisher, and a bookseller is and expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in the emerging Information Society. Furthermore, the various constraints to book development were identified while the paper advised on how the Book Industry can be further promoted in Nigeria. However, the paper concluded and made recommendations on how the Book sector can help in enhancing scholarship in the country

    Development of biodiverse production systems for the Netherlands

    No full text
    Dit proefschrift gaat over het ontwikkelen en toetsen van teeltsystemen met verschillende niveaus van biodiversiteit. Een eerste ontwerp werd besproken met belanghebbenden. Belanghebbenden (stakeholders) zijn personen betrokken bij de landbouw, zoals boeren, vertegenwoordigers van natuurbeheer, wetenschappers, mensen van landbouwadviesbureaus en beleidsmakers. Hun reacties zijn gebruikt om het ontwerp te verbeteren, maar vooral ook om indicatoren te ontwikkelen om de teeltsystemen te evalueren. Functionaliteit van de systemen werd getoetst in de gebieden economie, ecologie en sociologie

    Korevaar-Schoen-Sobolev spaces and critical exponents in metric measure spaces

    No full text
    We present developments in the theory of Korevaar-Schoen-Sobolev spaces on metric measure spaces. While this theory coincides with those of Cheeger and Shanmugalingam if the space is doubling and satisfies a Poincaré inequality, it offers new perspectives in the context of fractals for which the approach by weak upper gradients is inadequate.Previous version of the manuscript was used as Lecture Notes for the mini course hold at Texas A&M during the workshop Geometry and Analysis on Nonsmooth Spaces, August 8-12 2022. v6: Final version to appear in Ann.
