Sparse Grid Methods for Higher Dimensional Approximation
(2010-09-10)
Diese Arbeit befasst sich mit Dünngitterverfahren zur Lösung von höherdimensionalen Problemen. Sie zeigt drei neue Aspekte von Dünnen Gittern auf: Erweiterungen der elementaren Werkzeuge zur Arbeit mit Dünnen Gittern, eine ...
Joint methods in imaging based on diffuse image representations
(2010-08-31)
This thesis deals with the application and the analysis of different variants of the Mumford-Shah model in the context of image processing. In this kind of models, a given function is approximated in a piecewise smooth or ...
Numerische Simulation der Interaktion von inkompressiblen Zweiphasenströmungen mit Starrkörpern in drei Raumdimensionen
(2010-09-30)
In dieser Arbeit stellen wir erstmalig einen parallelen Löser für inkompressible Zweiphasenströmungen mit Oberflächenspannung in drei Raumdimensionen vor, der Masseerhaltung und hohe Konvergenzordnung vereint. Als zweite ...
Variational Methods in Shape Space
(2010-07-07)
This dissertation deals with the application of variational methods in spaces of geometric shapes. In particular, the treated topics include shape averaging, principal component analysis in shape space, computation of ...
Processing Elastic Surfaces and Related Gradient Flows
(2010-07-22)
Surface processing tools and techniques have a long history in the fields of computer graphics, computer aided geometric design and engineering. In this thesis we consider variational methods and geometric evolution problems ...
Modellierung und Existenztheorie dünner Filme auf evolvierenden Flächen
(2010-07-30)
In dieser Arbeit beschäftigen wir uns mit der Modellierung und Existenztheorie von dünnen Filmen inkompressibler, viskoser Flüssigkeiten auf evolvierenden, d.h. sich bewegenden, gekrümmten Flächen. Dünne Filme treten in ...
Motivic Fundamental Groups and Integral Points
(2010-07-16)
We give a motivic proof of finiteness of S-integral points on punctured projective line. We do this by studying torsors over different notions of unipotent fundamental groups attached to an open curve defined over a number ...
Contributions to Quantum Probability
(2010-07-07)
Chapter 1: On the existence of quantum representations for two dichotomic measurements. Under which conditions do outcome probabilities of measurements possess a quantum-mechanical model? This kind of problem is solved ...
Cohomology of classes of symbols and classification of traces on corresponding classes of operators with non positive order
(2010-07-09)
This thesis is devoted to the classification issue of traces on classical pseudo-differential operators with fixed non positive order on closed manifolds of dimension $n>1$. We describe the space of homogeneous functions ...
Fourier-Mukai transform for twisted sheaves
(2010-07-29)
In this thesis we study Fourier-Mukai transforms between derived categories of twisted sheaves. We show that some well known results about the classification of surfaces under derived categories extend to the derived ...
