Weak and Measure-Valued Solutions of the Incompressible Euler Equations
(2012-06-21)
This thesis is concerned with the existence problem for weak solutions of the incompressible Euler equations in arbitrary dimension, and with the relationship between weak solutions and other "very weak'' concepts of ...
Obstruction theory for operadic algebras
(2012-05-21)
We study obstruction theory for formality of chain operadic algebras. We construct a canonical class γA for an algebra A over a cofibrant chain operad P∞. This class takes values in the Gamma cohomology ...
Kippmoduln über deriviert speziell biseriellen Algebren
(2012-11-15)
Sei K ein algebraisch abgeschlossener Körper. Sei A eine endlich-dimensionale Algebra über K. Ein (klassischer) partieller Kippmodul über A ist ein endlich-dimensionaler A-Modul T der projektiven Dimension kleiner oder ...
Finite Element Methods for Geometric Problems
(2012-10-12)
In the herewith presented work we numerically treat geometric partial differential equations using finite element methods. Problems of this type appear in many applications from physics, biology and engineering use.

Adaptive numerical simulation of contact problems: Resolving local effects at the contact boundary in space and time
(2012-10-24)
This thesis is concerned with the space discretization of static and the space and time discretization of dynamic contact problems. In particular, we derive a new efficient and reliable residual-type a posteriori error ...
United Elliptic Homology
(2012-09-11)
We study the categories of modules over real K-theory and TMF. Inspired by work of Bousfield, we consider TMF-modules at the prime 3 which are relatively free with respect to TMF(2). We show that a large class of these can ...
On rigidity of the ring spectra PmS(p) and ko
(2012-09-14)
We study the rigidity question for modules over certain ring spectra. A stable model category is rigid if its homotopy category determines the Quillen equivalence type of the model category. Amongst others, we prove that ......
Über Starrheit der Ringspektren PmS(p) and ko
Wir beschäftigen uns mit der Frage ob die Kategorie der Moduln über bestimmten Ringspektren starr sind. Eine stabile ......
