    Sammanfattning : This dissertation is concerned with problem-solving in platform development. A problem isconceived of as an obstacle that needs to be overcome in order to reach a desired outcome,whereas a solution is denoted by the set of activities required to reach such an outcome. LÄS MER

  2. 2. The Double Obstacle Problem on Metric Spaces

    Detta är en avhandling från Matematiska institutionen

    Författare :Zohra Farnana; Linköpings universitet.; Linköpings universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metric space; nonlinear; obstacle problem; p-harmonic; potential theory; regularity; stability; MATHEMATICS; MATEMATIK;

    Sammanfattning : During the last decade, potential theory and p-harmonic functions have been developed in the setting of doubling metric measure spaces supporting a p-Poincar´e inequality. This theory unifies, and has applications in several areas of analysis, such as weighted Sobolev spaces, calculus on Riemannian manifolds and Carnot groups, subelliptic differential operators and potential theory on graphs.

  4. 4. The Double Obstacle Problem on Metric Spaces

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Zohra Farnana; Linköpings universitet.; Linköpings universitet.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : In this thesis we investigate the double obstacle problem for p-harmonic functions on metric spaces. We minimize the p-energy integral among all functions which have prescribed boundary values and lie between two given obstacles. LÄS MER
