  1. 6. Some modes of convergence and their application to homogenization and optimal composites design

    Författare :Anders Holmbom; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Homogenization; two-scale convergence; MATHEMATICS; MATEMATIK; Mathematics;

    Sammanfattning : In this thesis, we develop, extend, apply, and discuss a number of methods for the study of limits of sequences of functions and operators. The connection between the notion of two-scale convergence and more general concepts of convergence is investigated and some alternative classes of admissible test functions are characterized.

  2. 7. Regularity results in free boundary problems

    Författare :Gohar Aleksanyan; John Andersson; Darya Apushkinskaya; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Sammanfattning : This thesis consists of three scientific papers, devoted to the regu-larity theory of free boundary problems. We use iteration arguments to derive the optimal regularity in the optimal switching problem, and to analyse the regularity of the free boundary in the biharmonic obstacle problem and in the double obstacle problem.

  3. 8. Approximation and Calibration of Stochastic Processes in Finance

    Författare :Jonas Kiessling; Anders Szepessy; Jonathan Goodman; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : This thesis is a study of approximation and calibration of stochastic processes with applications in finance. It consists of an introduction and four research papers. The introduction is as an overview of the role of mathematics incertain areas of finance. LÄS MER

  4. 9. Approximation of Optimally Controlled Ordinary and Partial Differential Equations

    Författare :Mattias Sandberg; Anders Szepessy; Nils-Henrik Risebro; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : In this thesis, which consists of four papers, approximation of optimal control problems is studied. In Paper I the Symplectic Pontryagin method for approximation of optimally controlled ordinary differential equations is presented. LÄS MER

  5. 10. PDE methods for free boundary problems in financial mathematics

    Författare :Teitur Arnarson; Henrik Shahgholian; Diogo Gomes; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : We consider different aspects of free boundary problems that have financial applications. Papers I–III deal with American option pricing, in which case the boundary is called the early exercise boundary and separates the region where to hold the option from the region where to exercise it.
