1. Variational Methods for Moments of Solutions to Stochastic Differential Equations
Sammanfattning : Numerical methods for stochastic differential equations typically estimate moments of the solution from sampled paths. Instead, we pursue the approach proposed by A. Lang, S. Larsson, and Ch. LÄS MER
2. Numerical Approximation of Solutions to Stochastic Partial Differential Equations and Their Moments
Sammanfattning : The first part of this thesis focusses on the numerical approximation of the first two moments of solutions to parabolic stochastic partial differential equations (SPDEs) with additive or multiplicative noise. More precisely, in Paper I an earlier result (A. Lang, S. Larsson, and Ch. LÄS MER
3. Finite elements based on the piece-wise linear weight functions in contact problems
Sammanfattning : The Finite Element Method (FEM) has been applied widely in solving many engineering problems. The FEM is an approximate method, which makes use of a spatial discretization and a weighted residual formulation to arrive at a system of matrix equations. LÄS MER
