• #### Composition of Irreducible Morphisms in Quasi-Tubes ﻿

[OWP-2015-03] (Mathematisches Forschungsinstitut Oberwolfach, 2015-04-09)
We study the composition of irreducible morphisms between indecomposable modules lying in quasi-tubes of the Auslander-Reiten quivers of artin algebras $A$ in relation with the powers of the radical of their module category ...
• #### Discrete Translates in Lp (R) ﻿

[OWP-2015-09] (Mathematisches Forschungsinstitut Oberwolfach, 2015-06-18)
A set $\Lambda$ is called $p$-spectral if there is a function $g \in L^p (\mathbb{R})$ such that all $\Lambda$-translates $\{g(t-\lambda),\lambda \in \Lambda\}$ span $L^p(\mathbb{R})$. We prove that exponentially small ...
• #### Gibbs measures associated to the integrals of motion of the periodic derivative nonlinear Schrödinger equation ﻿

[OWP-2015-04] (Mathematisches Forschungsinstitut Oberwolfach, 2015-05-18)
• #### Realizing Spaces as Classifying Spaces ﻿

[OWP-2015-01] (Mathematisches Forschungsinstitut Oberwolfach, 2015-04-10)
Which spaces occur as a classifying space for fibrations with a given fibre? We address this question in the context of rational homotopy theory. We construct an infinite family of finite complexes realized (up to rational ...
• #### Simulation of Multibody Systems with Servo Constraints through Optimal Control ﻿

[OWP-2015-18] (Mathematisches Forschungsinstitut Oberwolfach, 2015)
We consider mechanical systems where the dynamics are partially constrained to prescribed trajectories. An example for such a system is a building crane with a load and the requirement that the load moves on a certain path. ...
• #### Virtual Polytopes ﻿

[OWP-2015-02] (Mathematisches Forschungsinstitut Oberwolfach, 2015-04-10)
Originating in diverse branches of mathematics, from polytope algebra and toric varieties to the theory of stressed graphs, virtual polytopes represent a natural algebraic generalization of convex polytopes. Introduced as ...
