1. On vanishing-curvature extensions of Lorentzian metrics
Sammanfattning : .... LÄS MER
2. Positive vector bundles in complex and convex geometry
Sammanfattning : This thesis concerns various aspects of the geometry of holomorphic vector bundles and their analytical theory which all, vaguely speaking, are related to the notion of positive curvature in general, and L^2-methods for the dbar-equation in particular. The thesis contains four papers. LÄS MER
3. Noncommutative Riemannian Geometry of Twisted Derivations
Sammanfattning : A twisted derivation is a generalized derivative satisfying a twisted version of the ordinary Leibniz rule for products. In particular, a (σ, τ )-derivation on an algebra A, is a derivation where Leibniz rule is twisted by two endomorphisms σ and τ on A. LÄS MER
4. Numerical methods for the Navier–Stokes equations applied to turbulent flow and to multi-phase flow
Sammanfattning : This thesis discusses the numerical approximation of flow problems, in particular the large eddy simulation of turbulent flow and the simulation of laminar immiscible two-phase flow. The computations for both applications are performed with a coupled solution approach of the Navier-Stokes equations discretized with the finite element method. LÄS MER
