DN2281 Computational Methods for Stochastic Differential Equations, spring 20127.5 CreditsFormal description, that is, the text on the student web. Most recent changes on 30 June 2012. Re-examThe re-exam will take place on Friday August 24, at 13-17, in seminar room 4523, Lindstedtsvägen 3, floor 5.
NewsThe written May 29 exam has been corrected. You can pick it up at studentexpeditionen. They are open between 10 and 11 each day until Friday June 29.The deadline for homework 4 has been extended to the lecture Tuesday April 17. Note, however that the deadline for homework 5 is still the lecture Tuesday April 24. Homework 4 is now (April 3) changed slightly, so that the initial condition for S is given. Course QuestionnaireTeaching and ExaminationThe first lecture is held January 17 in room D42. Examination is by homework, presentation, and a final written exam. The homework and presentations are carried out by groups of students. Each group hand in a report on each assignment.TeacherMattias Sandberg, room 4525, CSC, Lindstedtsvägen 3, floor 5.

The definition uses numerical schemes, and in the process we also obtain convergence results for these schemes. Expected values as functions of starting positions for SDEs are given by solutions to partial differential equations. We will consider the two different possibilities of finding such expected values by Monte Carlo simulation and finite difference schemes.Applications are e.g. finance, where stock prices are modelled using SDEs, and molecular dynamics, where SDEs are used to model e.g. systems with constant temperature. Optimal control will also be discussed in the course. It is needed e.g. in the optimal hedging problem of optimizing a portfolio. Exam PaperA substantial part of the exam will be based on the following list of questions.LiteratureWe will use the lecture notes, by Jesper Carlsson, Kyong-Sook Moon, Anders Szepessy, Raul Tempone, and Georgios Zouraris.HomeworkHomework 1 on Ito integrals, due the lecture Tuesday January 31.Homework 2 on Ito and Stratonovich, due the lecture Friday February 24. Homework 3 on Feynman-Kac and Options, due the lecture Tuesday March 20. Homework 4 on Monte Carlo and Options, due the lecture Tuesday April 17. Homework 5 on dynamic programming, due the lecture Tuesday April 24.
