  1. 6. Error Estimation and Adaptive Methods for Molecular Dynamics

    Author : Ashraful Kadir; Anders Szepessy; Emanuel Rubensson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This  thesis consists of two  papers that  concern error estimates for the Born-Oppenheimer molecular dynamics, and adaptive algorithms for the Car-Parrinello and Ehrenfest molecular dynamics. In Paper I, we study error estimates for Born-Oppenheimer molecular dynamics with  nearly crossing potential  surfaces. READ MORE

  5. 10. Calibration and Hedging in Finance

    Author : Love Lindholm; Anders Szepessy; Erik Lindström; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; finance; local volatility; calibration; optimal control; hedging; quadratic hedging; equity; index; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Abstract : This thesis treats aspects of two fundamental problems in applied financial mathematics: calibration of a given stochastic process to observed marketprices on financial instruments (which is the topic of the first paper) and strategies for hedging options in financial markets that are possibly incomplete (which is the topic of the second paper).Calibration in finance means choosing the parameters in a stochastic process so as to make the prices on financial instruments generated by the process replicate observed market prices.
