  3. 2. On boundary value problems for intracellular subdiffusion and signaling pathways, and for geometric flows

    Författare :Tobias Gebäck; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; boundary value problems; diffusion-reaction equations; signaling pathways; anomalous diffusion; pseudo-differential equations; fluorescence correlation spectroscopy; immersed interface method; Boolean grids; mean curvature flow; pseudo-differential equations; boundary value problams; flourescence correlation spectroscopy;

    Sammanfattning : The main part of this thesis concerns mathematical models for diffusion of proteins inside cells, including reactions between the proteins. Initially, such models are applied to describe signaling pathways in yeast cells, and the properties of the model are studied, especially in relation to models that do not include diffusion. LÄS MER

  4. 3. Parallell finite element analysis of periodic boundary value problems

    Författare :Ola Kristensson; Mekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

  5. 4. Selected Problems in Financial Mathematics

    Författare :Erik Ekström; Johan Tysk; Svante Janson; Lane P. Hughston; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical analysis; American options; convexity; monotonicity in the volatility; robustness; optimal stopping; parabolic equations; free boundary problems; volatility; Russian options; game options; excessive functions; superreplication; smooth fit; Matematisk analys; Mathematical analysis; Analys;

    Sammanfattning : This thesis, consisting of six papers and a summary, studies the area of continuous time financial mathematics. A unifying theme for many of the problems studied is the implications of possible mis-specifications of models. Intimately connected with this question is, perhaps surprisingly, convexity properties of option prices. LÄS MER

  7. 5. Initial-Boundary-Value Problems for the Stokes and Navier–Stokes Equations on Staggered Grids

    Författare :Jonas Nilsson; Bertil Gustafsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Stokes equations; Navier-Stokes equations; boundary conditions; staggered grids; higher-order methods; Numerical Analysis; Numerisk analys;

    Sammanfattning : In the first part of the thesis various types of boundary conditions for the steady state Stokes equations are considered. We formulate the boundary conditions in a new way, such that the boundary value problem becomes non-singular, and derive estimates of the solution. LÄS MER
