Obstruction theory for operadic algebras
Dimitrova, Boryana (20120521)We study obstruction theory for formality of chain operadic algebras. We construct a canonical class γ_{A} for an algebra A over a cofibrant chain operad P_{∞}. This class takes values in the Gamma cohomology ... 
Ocular Onchocerciasis: The Role of TollLike Receptor2 and Interferonγ
Gentil, Katrin (20100317)River Blindness is still highly prevalent in subsaharan Africa with millions of people suffering from the infection with Onchocerca volvulus. This filarial worm harbors the endosymbiont Wolbachia which was ... 
OffLabelUse von Arzneimitteln in der Palliativmedizin
Hafner, Katrin (20130507)Es steht außer Frage, dass die gesundheitliche Versorgung unserer Gesellschaft durch den medizinischen Fortschritt in den letzten Jahrzehnten enorm gesteigert wurde. Dabei ist der Schwerpunkt dieser Entwicklung auf Heilung ... 
Old Globular Clusters in Dwarf Irregular Galaxies
Georgiev, Iskren Y. (2008)One of the most pressing questions in astrophysics to date is resolving the history of galaxy assembly and their subsequent evolution. In the currently popular hierarchical merging” scenario, massive galaxies are believed ...

Oligozäne Beckendynamik und Sequenzstratigraphie am Südrand des Nordwesteuropäischen Tertiärbeckens
Nickel, Elke (2004)Durch die Analyse von Bohrdaten aus 230 Explorations und Forschungsbohrungen wird für die oligozäne Sedimentfüllung am Südrand des Nordwesteuropäischen Tertiärbeckens zwischen Belgien im Westen und SachsenAnhalt im Osten ... 
On a kinetic equation arising in weak turbulence theory for the nonlinear Schrödinger equation
Kierkels, Arthur Hubertus Martinus (20161222)We present a study of weak solutions to a kinetic equation of coagulationfragmentation type. This quadratic equation (QWTE) is the leading order approximation for long times to the isotropic spacehomogeneous weak turbulence ... 
On affine DeligneLusztig varieties for GL_{n}
Mierendorff, Eva (2005)In the first part of this thesis we study the global structure of moduli spaces of quasiisogenies of pdivisible groups introduced by Rapoport and Zink. We determine their dimensions and their sets of connected components ... 
On Analysis of some Nonlinear Systems of Partial Differential Equations of Continuum Mechanics
Steinhauer, Mark (2003)In this thesis we consider systems of partial differential equations of continuum mechanics and analyze regularity properties of their weak solutions.
The first chapter contains a detailed introduction and reviews ... 
On Approximability of Bounded Degree Instances of Selected Optimization Problems
Schmied, Richard (20130807)In order to cope with the approximation hardness of an underlying optimization problem, it is advantageous to consider specific families of instances with properties that can be exploited to obtain efficient approximation ... 
On Approximability, Convergence, and Limits of CSP Problems
Markó, Roland (20160916)This thesis studies dense constraint satisfaction problems (CSPs), and other related optimization and decision problems that can be phrased as questions regarding parameters or properties of combinatorial objects such as ... 
On arithmetic families of filtered φmodules and crystalline representations
Hellmann, Eugen (20110510)We consider stacks of filtered phimodules over rigid analytic and adic spaces. We show that these modules parametrize padic Galois representations of the absolute Galois group of a padic field with varying coefficients ... 
On arithmetic properties of Fuchsian groups and Riemann surfaces
Kucharczyk, Robert Anselm (20150211)In this thesis, Riemann surfaces and their fundamental groups are studied from an arithmetic point of view. First the image of the absolute Galois group of a number field under Grothendieck's representation with values in ... 
On Cells and Agents: Geosimulation of Urban Sprawl in Western Germany by Integrating Spatial and NonSpatial Dynamics
Rienow, Andreas (20140718)Urban sprawl is one of the most challenging landuse and landcover changes in Germany implicating numerous consequences for the anthropogenic and geobiophysical spheres. While the population and job growth rates of most ... 
On discrete surfaces: Enumerative geometry, matrix models and universality classes via topological recursion
GarciaFailde, Elba (20190321)The main objects under consideration in this thesis are called maps, a certain class of graphs embedded on surfaces. We approach our study of these objects from different perspectives, namely bijective combinatorics, matrix ... 
On GIT Compactified Jacobians via Relatively Complete Models and Logarithmic Geometry
Bellardini, Alberto (20140709)In this thesis we study modular compactifications of Jacobian varieties attached to nodal curves.
Unlike the case of smooth curves, where the Jacobians are canonical, modular compact objects, these compactifications ... 
On moduli spaces of Riemann surfaces: new generators in their unstable homology and the homotopy type of their harmonic compactification
Boes, Felix Jonathan (20180710)By M_g(m,n) we denote the moduli space of conformal structures on an oriented compact cobordism S_g(m,n) of genus g greater or equal 0 and with m+n greater or equal 0 enumerated, parametrized boundary components of which ... 
On Multilevel Methods Based on NonNested Meshes
Dickopf, Thomas (20101215)This thesis is concerned with multilevel methods for the efficient solution of partial differential equations in the field of scientific computing. Further, emphasis is put on an extensive study of the information transfer ... 
On Problems Related To Galaxy Formation
Abdullah, Ahmed Hasan (20160517)The main idea of the underlying PhD study is to trace the history of the assembly of galaxies and of their subsequent evolution. We approach this issue in two ways: 1) by studying galaxy spin and 2) by studying the oldest ... 
On quotients of ω* and automorphisms of P(ω)/fin that preserve or invert the shift
Silveira Salles, Tomás (20160530)The first part of the dissertation concerns the space ω*:=βω\ω and its quotients. A 2002 result from Bella, Dow, Hart, Hrusak, van Mill and Ursino implies that homeomorphisms between 0dimensional secondcountable Hausdorff ... 
On Rho Invariants of Fiber Bundles
Bohn, Michael (20090721)Using adiabatic limits of Eta invariants, Rho invariants of the total space of a fiber bundle are investigated. One concern is to formulate the aspects of local index theory for families of Dirac operator in terms of the ...
