Asymptotically Hyperbolic Metrics on Unit Ball Admitting Multiple Horizons [PDF]
Proceedings AMS 136 (2008), 2007 In this paper, we construct an asymptotically hyperbolic metric with scalar curvature -6 on unit ball $\mathbf{D}^3$, which contains multiple horizons.Comment ...

Triangular ratio metric in the unit disk [PDF]
Complex Variables and Elliptic Equations, 2021 The triangular ratio metric is studied in a domain $G\subsetneq\mathbb{R}^n$, $n\geq2$. Several sharp bounds are proven for this metric, especially, in the case where the domain is the unit disk of the complex plane. The results are applied to study the H lder continuity of quasiconformal mappings.

Collapse of unit horizontal bundles equipped with a metric of Cheeger-Gromoll type [PDF]
arXiv, 2007 We study unit horizontal bundles associated with Riemannian submersions. First we investigate metric properties of an arbitrary unit horizontal bundle equipped with a Riemannian metric of the Cheeger-Gromoll type. Next we examine it from the Gromov-Hausdorff convergence theory point of view, and we state a collapse theorem for unit horizontal bundles ...

Metric Dimension for Gabriel Unit Disk Graphs is NP-Complete [PDF]
Algorithmic Aspects of Wireless Sensor Networks, 2013 We show that finding a minimal number of landmark nodes for a unique virtual addressing by hop-distances in wireless ad-hoc sensor networks is NP-complete even if the networks are unit disk graphs that contain only Gabriel edges.

Radial balanced metrics on the unit ball of the Kepler manifold [PDF]
arXiv, 2020 We show that there is no radial balanced metric on the unit ball of the Kepler manifold with not too wild boundary behavior. Additionally, we identify explicitly the weights corresponding to radial metrics with such boundary behavior which satisfy the balanced condition as far as germs at the boundary are concerned.

Radial balanced metrics on the unit disk
Journal of Geometry and Physics, 2010 Let $ $ be a strictly plurisubharmonic and radial function on the unit disk ${\cal D}\subset {\complex}$ and let $g$ be the \K metric associated to the \K form $ =\frac{i}{2}\partial\bar\partial $. We prove that if $g$ is $g_{eucl}$-balanced of height 3 (where $g_{eucl}$ is the standard Euclidean metric on ${\complex}={\real}^2$), and the function ...

Paracontact metric structures on the unit tangent sphere bundle [PDF]
, 2013 Starting from $g$-natural pseudo-Riemannian metrics of suitable signature on the unit tangent sphere bundle $T_1 M$ of a Riemannian manifold $(M,\langle,\rangle)$, we construct a family of paracontact metric structures.

Why pitch sensitivity matters : event-related potential evidence of metric and syntactic violation detection among spanish late learners of german [PDF]
Frontiers in Psychology, 2011 Event-related potential (ERP) data in monolingual German speakers have shown that sentential metric expectancy violations elicit a biphasic ERP pattern consisting of an anterior negativity and a posterior positivity (P600).

Unit-cell volume change as a metric of radiation damage in crystals of macromolecules [PDF]
Journal of Synchrotron Radiation, 2002 The use of third-generation synchrotron sources has led to renewed interest in the effect that ionizing radiation has on crystalline biological materials. Simple criteria have been sought to study the effects systematically.
