  2. 1. On the asymptotic spectral distribution of random matrices : closed form solutions using free independence

    Author : Jolanta Maria Pielaszkiewicz; Dietrich von Rosen; Martin Singull; Maciej A. Nowak; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spectral distribution; R-transform; Stieltjes transform; Free probability; Freeness; Asymptotic freeness;

    Abstract : The spectral distribution function of random matrices is an information-carrying object widely studied within Random matrix theory. In this thesis we combine the results of the theory together with the idea of free independence introduced by Voiculescu (1985). READ MORE

  4. 2. Asymptotic Problems on Homogeneous Spaces

    Author : Anders Södergren; Andreas Strömbergsson; Dennis Hejhal; Jens Marklof; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analysis on homogeneous spaces; hyperbolic manifolds; spectral theory; equidistribution; the space of lattices; length statistics; Poisson process; moments; Epstein zeta function; value distribution; height function.; MATHEMATICS; MATEMATIK; Mathematics; Matematik;

    Abstract : This PhD thesis consists of a summary and five papers which all deal with asymptotic problems on certain homogeneous spaces. In Paper I we prove asymptotic equidistribution results for pieces of large closed horospheres in cofinite hyperbolic manifolds of arbitrary dimension. READ MORE

  5. 3. Asymptotic Expansions for Perturbed Discrete Time Renewal Equations

    Author : Mikael Petersson; Dmitrii Silvestrov; Ola Hössjer; Henrik Hult; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Renewal equation; Perturbation; Asymptotic expansion; Regenerative process; Quasi-stationary distribution; Risk process; Ruin probability;

    Abstract : In this thesis we study the asymptotic behaviour of the solution of a discrete time renewal equation depending on a small perturbation parameter. In particular, we construct asymptotic expansions for the solution of the renewal equation and related quantities. READ MORE

  7. 5. Asymptotic Expansions of Crossing Rates of Stationary Random Processes

    Author : Oskar Hagberg; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; actuarial mathematics; Statistik; operationsanalys; aktuariematematik; programming; operations research; Matematik; Statistics; sea elevation; Mathematics; asymptotic expansions; wave crest hight distribution; Saddle point approximations; Crossing rate; programmering;

    Abstract : The crossing rate of a stationary random process is a valuble tool when studying crest hight distributions and maxima of sea level elevation. This thesis considers two approximation techinques for cases when the crossing rate cannot be exactly computed. READ MORE
