We give conditions which imply that a complete noncompact manifold with quadratic curvature decay has finite topological type. In particular, we find links between the topology of a manifold with quadractic curvature decay and some properties of the asymptotic cones of such a manifold.

We deal with a solid manifold block and a laminated manifold block that are used for connecting hydraulic components. They are useful for reducing the space and weight of hydraulic systems. We investigate pressure drops of their pipe flow with computational fluid dynamics (CFD) and compare those of two types. The majority of all pressure drops in both types is pressure drop at corners. In solid...

The papers in this special issue on communication in health care can be summarized in one easy and powerful message: communication is the royal pathway to patient-centered medicine. Approached from different angles, the linkage between communication and patient-centered medicine is the common theme that is covered by all authors. Underlying are two distinct assumptions: the first is, that patie...

The pairing can be viewed as giving families of invariants of hyperk\"ahler manifolds or as giving families of 3-manifold invariants. In the first approach, one hopes to derive theorems about the geometry of hyperk\"ahler manifolds (this has been initiated by Hitchin and Sawon). In the second approach, the invariants obtained are finite-type invariants, so their computation factorises into two ...

The aim of this paper is to devise a Chern –Weil-type construction for a Finsler manifold (M,L) which is determined only by the manifold M and by the Finslerian fundamental function L.

We show that M-theory compactified on a compact Joyce 8-manifold of Spin(7)holonomy, which yields an effective theory in D = 3 with N = 1 supersymmetry, admits at some special points in it moduli space a description in terms of type IIA theory on an orientifold of compact Joyce 7-manifold of G2-holonomy. We find the evidence in favour of this duality by computing the massless spectra on both M-...

Zusammenfassung Playbacktheater ist eine Form des Improvisationstheaters, die sich aus Psychodrama, Stegreifspiel und mündlichen Erzähltraditionen entwickelt hat. Dieser Artikel der Zeitschrift für Psychodrama Soziometrie beschreibt den Einsatz im Rahmen sozialen Konfliktmanagements. Es wird gezeigt, wie Rahmen, Regeln Rituale Playbacktheaters es Konfliktparteien erleichtern können, in einem mo...

We prove that any arithmetic hyperbolic n-manifold of simplest type can either be geodesically embedded into an arithmetic hyperbolic (n+ 1)-manifold or its universal mod 2 abelian cover can.

We find a necessary and sufficient condition for a compact 7-manifold to admit a G̃2-structure. As a result we find a sufficient condition for an open 7-manifold to admit a closed 3-form of G̃2-type.
