  4. 2. On complex convexity

    Author : David Jacquet; Mikael Passare; Peter Pflug; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ℂ-convex; Linearly convex; Charathéodory metric; Kobayshi metric; MATHEMATICS; MATEMATIK; matematik; Mathematics;

    Abstract : 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. READ MORE

    Abstract : This thesis consists of an introduction and four research papers related to free boundary problems and systems of fully non-linear elliptic equations.Paper A and Paper B prove optimal regularity of solutions to general elliptic and parabolic free boundary problems, where the operators are fully non-linear and convex.

  7. 5. Fixed-Parameter Algorithms for Optimal Convex Partitions and Other Results

    Author : Magdalene Grantson Borgelt; Data Vetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; control; Datalogi; numerical analysis; Convex Partition; Computer science; Triangulation; kontroll; system; numerisk analys; systems; Fixed-Parameter Algorithm; Spanning Tree;

    Abstract : In this thesis I study two-dimensional geometric optimization problems for which it is difficult to find efficient, exact, deterministic algorithms. All known solutions to these problems require time that is exponential in the total size of the input. READ MORE
