On sets with unit Hausdorff density in homogeneous groups

open access: yesForum of Mathematics, Sigma, 2023
It is a longstanding conjecture that given a subset E of a metric space, if E has unit $\mathscr {H}^{\alpha }\llcorner E$ -density almost everywhere, then E is an $\alpha $ -rectifiable set. We prove this conjecture under the assumption that

Cusps and the family hyperbolic metric [PDF]

open access: yes, 2007
The hyperbolic metric for the punctured unit disc in the Euclidean plane is singular at the origin. A renormalization of the metric at the origin is provided by the Euclidean metric. For Riemann surfaces there is a unique germ for the isometry class of a

MUTT: Metric Unit TesTing for Language Generation Tasks

open access: yesAnnual Meeting of the Association for Computational Linguistics, 2016
Precise evaluation metrics are important for assessing progress in high-level language generation tasks such as machine translation or image captioning. Historically, these metrics have been evaluated using correlation with human judgment. However, human-

Quantized Gromov-Hausdorff distance [PDF]

open access: yes, 2005
A quantized metric space is a matrix order unit space equipped with an operator space version of Rieffel's Lip-norm. We develop for quantized metric spaces an operator space version of quantum Gromov-Hausdorff distance.

Generalized Ricci solitons and Einstein metrics on weak K-contact manifolds

open access: yesCommunications in Analysis and Mechanics, 2023
We study so-called "weak" metric structures on a smooth manifold, which generalize the metric contact and $ K $-contact structures and allow a new look at the classical theory.

Another extension of the disc algebra [PDF]

open access: yes, 2010
We identify the complex plane C with the open unit disc D={z:|z| z/(1+|z|). This leads to a compactification $\bar{C}$ of C, homeomorphic to the closed unit disc. The Euclidean metric on the closed unit disc induces a metric d on $\bar{C}$.

The Quaternionic Hardy Space and the Geometry of the Unit Ball

open access: yesBruno Pini Mathematical Analysis Seminar, 2015
The quaternionic Hardy space of slice regular functions H2(B) is a reproducing kernel Hilbert space. In this note we see how this property can be exploited to construct a Riemannian metric on the quaternionic unit ball B and we study the geometry arising

Passive Radar at the Roadside Unit to Configure Millimeter Wave Vehicle-to-Infrastructure Links [PDF]

open access: yesIEEE Transactions on Vehicular Technology, 2019
Millimeter wave (mmWave) vehicular channels are highly dynamic, and the communication link needs to be reconfigured frequently. In this work, we propose to use a passive radar receiver at the roadside unit to reduce the training overhead of establishing ...
