  1. 1. Nonparametric Statistical Inference for Entropy-type Functionals

    Författare :David Källberg; Oleg Seleznjev; Timo Koski; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; entropy estimation; Rényi entropy; divergence estimation; quadratic density functional; U-statistics; consistency; asymptotic normality; Poisson convergence; stationary m-dependent sequence; inter-point distances; entropy maximizing distribution; two-sample problem; approximate matching; Mathematical Statistics; matematisk statistik;

    Sammanfattning : In this thesis, we study statistical inference for entropy, divergence, and related functionals of one or two probability distributions. Asymptotic properties of particular nonparametric estimators of such functionals are investigated. We consider estimation from both independent and dependent observations. LÄS MER

  3. 2. Defects, renormalization and conformal field theory

    Författare :Alexander Söderberg Rousu; Agnese Bissi; Pedro Liendo; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; defects; boundaries; replica twist defect; conformal field theory; quantum field theory; Coleman-Weinberg mechanism; renormalization group flows; Theoretical Physics; Teoretisk fysik;

    Sammanfattning : Defects in quantum field theories appear in many different contexts and are of great physical interest. Among other things, defects are used to describe the Kondō effect in condensed matter, confinement in quantum chromodynamics, Rényi entropy in quantum information and cosmic strings in string theory.
