Dagmar Barth - Weingarten
This paper presents the concept of the "participant perspective" as an approach to the study of spoken language. It discusses three aspects of this concept and shows that they can offer helpful tools in spoken language research. Employing the participant perspective provides us with an alternative to many of the approaches currently in use in the study of spoken language in that it favours smal...
متن کاملOn linear Weingarten surfaces
In this paper we study surfaces in Euclidean 3-space that satisfy a Weingarten condition of linear type as κ1 = mκ2 + n, where m and n are real numbers and κ1 and κ2 denote the principal curvatures at each point of the surface. We investigate the possible existence of such surfaces parametrized by a uniparametric family of circles. Besides the surfaces of revolution, we prove that not exist mor...
متن کاملOn Weingarten-Volterra defects
The kinematic theory of Weingarten-Volterra line defects is revisited, both at small and finite deformations. Existing results are clarified and corrected as needed, and new results are obtained. The primary focus is to understand the relationship between the disclination strength and Burgers vector of deformations containing a Weingarten-Volterra defect corresponding to different cut-surfaces.
متن کاملLinear Weingarten Surfaces in R
In this paper we study properties of linear Weingarten immersions and graphs related to non-existence problems and behaviour of its curvatures. The main results are obtained giving a harmonic representation of linear Weingarten surfaces and by proving optimal estimates of the height and curvatures that the immersion must satisfy, characterizing the spherical caps as the only ones achieving thes...
متن کاملClosed Weingarten Hypersurfaces in Semi-riemannian Manifolds
The existence of closed hypersurfaces of prescribed curvature in semi-riemannian manifolds is proved provided there are barriers.
