    Sammanfattning : Paper 1 : A geometrical version of Hardy's inequality for W_0^{1,p}(D).The aim of this article is to prove a Hardy-type inequality, concerning functions in W_0^{1,p}(D) for some domain D in R^n, involving the volume of D and the distance to the boundary of D. The inequality is a generalization of a previously proved inequality by M. and T. LÄS MER

  4. 3. Lipoprotein-associated phospholipase A2 (Lp-PLA2) Impact and role as cardiovascular risk marker

    Författare :Margaretha Persson; Internmedicin - epidemiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiovascular disease; cohort study; epidemiology; Lp-PLA2; PLA2G7 gene; metabolic syndrome; risk factor; stroke;

    Sammanfattning : Lipoprotein-associated phospholipase A2 (Lp-PLA2) is today considered a novel specific vascular inflammatory biomarker. The general aim of this thesis was to study the role and impact of Lp-PLA2 as cardiovascular (CV) risk marker in an epidemiologic perspective. LÄS MER

  5. 4. Recent Studies on Lp-Norm Estimation

    Författare :Hans Nyquist; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : When estimating the parameters in a linear regression model, the method of least squares (L^-norm estimator) is often used. When thè residuals are independent and identically normally distributed, the least squares estimator is BLUE as well as equivalent to the maximum likelihood estimator. LÄS MER

  7. 5. Riesz potentials and Riesz transforms in local Lp-spaces

    Författare :Johan Thim; Nils Dencker; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : We consider the following equation for the Riesz potential of order one:The analysis is done in local Lp and Sobolev spaces, where the topologies are described by a family of semi-norms depending on a positive real parameter. Uniqueness and existence results are proved and asymptotic properties of solutions near the origin are established. LÄS MER
