  3. 2. Gaussian fluctuations in some determinantal processes

    Författare :Jonas Hägg; Kurt Johansson; Alexander Soshnikov; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Random matrices; limit theorems; MATHEMATICS; MATEMATIK;

    Sammanfattning : This thesis consists of two parts, Papers A and B, in which some stochastic processes, originating from random matrix theory (RMT), are studied. In the first paper we study the fluctuations of the kth largest eigenvalue, xk, of the Gaussian unitary ensemble (GUE). LÄS MER

  4. 3. Point counts and the cohomology of moduli spaces of curves

    Författare :Jonas Bergström; Carel Faber; Lothar Göttsche; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : n this thesis we count the number of points defined over finite fields of certain moduli spaces of pointed curves. The aim is primarily to gain cohomological information. Paper I is joint work with Orsola Tommasi. Here we present details of the method of finding cohomological information on moduli spaces of curves by counting points. LÄS MER
