  2. 2. On complex convexity

    Detta är en avhandling från Stockholm : Matematiska institutionen

    Författare :David Jacquet; Mikael Passare; Peter Pflug; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ℂ-convex; Linearly convex; Charathéodory metric; Kobayshi metric; MATHEMATICS; MATEMATIK; matematik; Mathematics;

    Sammanfattning : This thesis is about complex convexity. We compare it with other notions of convexity such as ordinary convexity, linear convexity, hyperconvexity and pseudoconvexity. We also do detailed study about ℂ-convex Hartogs domains, which leads to a definition of ℂ-convex functions of class C1. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; complex analysis; convex analysis; currents; Lelong numbers; tropical geometry; L^2-estaimtes; Legendre transform; intersection theory; real Monge-Ampere operators; plurisubharmonic functions; integrability index; L^2-estaimtes; plurisubharmonic functions; tropical geometry; Legendre transform; integrability index; convex analysis; currents; Lelong numbers; real Monge-Ampere operators; intersection theory;

    Sammanfattning : This thesis treats different aspects of convexity, both real and complex. On the real side,we study convexity in relation with certain currents. On the complex side, we study the singularitiesof plurisubharmonic functions. LÄS MER

  5. 5. Nonparametric Functional Estimation under Order Restrictions

    Detta är en avhandling från Centre for Mathematical Sciences, Lund University

    Författare :Dragi Anevski; [2000]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; monotonicity; convexity; deconvolution; kernel smoothing; NPMLE; long range dependence; greatest convex minorant; mixing; Density estimation; limit distribution.; regression; Mathematics; Matematik;

    Sammanfattning : This thesis consists of three papers (Papers A-C) on problems in nonparametric functional estimation, in particular density and regression function estimation and deconvolution, under order assumptions. Pointwise limit distribution results are stated for the obtained estimators, which include isotonic regression estimates, nonparametric maximum likelihood estimates of monotone densities, estimates of convex regression and density functions and deconvolution estimates.
