16. Rotational effects in water waves
Sammanfattning : Abstract: This thesis consists of four papers related to various aspects of water waves with vorticity. Paper I: Symmetry of steady periodic gravity water waves with vorticity. LÄS MER
17. High Order Finite Difference Methods in Space and Time
Sammanfattning : In this thesis, high order accurate discretization schemes for partial differential equations are investigated. In the first paper, the linearized two-dimensional Navier-Stokes equations are considered. LÄS MER
18. On Lorentz Invariance, Regularity and Global Existence for Kinetic Equations
Sammanfattning : [A1] Regularity of the gain term and strong L1 convergence to equilibrium for the relativistic Boltzmann equation. The main purpose of the paper is to show that the gain term of the relativistic collision operator is regularizing. This is a generalization of P.L. LÄS MER
19. Existence results for noncoercive incremental contact problems with Coulomb friction
Sammanfattning : Friction is a phenomenon which is present in most mechanical devices and frequently encountered in everyday life. Noncoercive incremental contact problems with Coulomb friction constitute an important class of friction problems due to their frequent occurrence in mechanical engineering. LÄS MER
20. Computer-Assisted Proofs and Other Methods for Problems Regarding Nonlinear Differential Equations
Sammanfattning : This PhD thesis treats some problems concerning nonlinear differential equations. In the first two papers computer-assisted proofs are used. The differential equations there are rewritten as fixed point problems, and the existence of solutions are proved. LÄS MER
