Anisotrope Verfahren in der Bildverarbeitung: Gradientenflüsse, Level-Sets und Narrow Bands: Gradientenflüsse, Level-Sets und Narrow Bands
(2008)
Isotrope Glättungs- und Restaurierungsverfahren neigen dazu, Isoflächen abzurunden. Für beispielsweise ecken- oder kantenerhaltendes Glätten oder Restaurieren sind sie nicht geeignet. Stattdessen können anisotrope ...
Rigidity and Exotic Models for the K-local Stable Homotopy Category
(2007)
When two stable model categories C and D are Quillen equivalent, their homotopy categories Ho(C) and Ho(D) are equivalent as triangulated categories. But is the converse also true?
For the stable homotopy category ...
For the stable homotopy category ...
New Approach to Arakelov Geometry
(2007)
This work is dedicated to a new completely algebraic approach to Arakelov geometry, which doesn't require the variety under consideration to be generically smooth or projective. In order to construct such an approach we ...
Maschinelles Lernen durch Funktionsrekonstruktion mit verallgemeinerten dünnen Gittern
(2004)
Diese Arbeit beschäftigt sich mit einem neuen Ansatz für das Klassifikationsproblem beim Maschinellen Lernen durch Funktionsrekonstruktion. Es basiert auf dem Zugang des Regularisierungsnetzwerks, aber im Gegensatz zu ...
Interpolation categories for homology theories
(2004)
For a given homological functor, that satisfies some technical assumptions, from a triangulated category, that has an underlying model category, to an abelian category with enough injectives we construct a tower interpolation ...
Approximation Complexity of Optimization Problems: Structural Foundations and Steiner Tree Problems
(2004)
In this thesis we study the approximation complexity of the Steiner Tree Problem and related problems as well as foundations in structural complexity theory. The Steiner Tree Problem is one of the most fundamental problems ...
Adaptive Scattered Data Fitting with Tensor Product Spline-Wavelets
(2005)
The core of the work we present here is an algorithm that constructs a least squares approximation to a given set of unorganized points. The approximation is expressed as a linear combination of particular B-spline wavelets. ...
On affine Deligne-Lusztig varieties for GLn
(2005)
In the first part of this thesis we study the global structure of moduli spaces of quasi-isogenies of p-divisible groups introduced by Rapoport and Zink. We determine their dimensions and their sets of connected components ...
The supersingular locus of the Shimura variety of GU(1,s)
(2005)
In this paper I study the supersingular locus of the reduction modulo p of the Shimura variety of GU(1,s) in the case of an inert prime p. Using Dieudonné theory I define a stratification of the ...
Some Applications of the Weighted Combinatorial Laplacian
(2005)
The weighted combinatorial Laplacian of a graph is a symmetric matrix which is the discrete analogue of the Laplacian operator. In this thesis, we will study a new application of this matrix to matching theory yielding a ...
