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

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.

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

ETNOMATEMATIKA: TRADISI PENGUKURAN MASYARAKAT SUKU SASAK DAN POTENSI PENGINTEGRASIANNYA DALAM PEMBELAJARAN MATEMATIKA

open access: yesAksioma: Jurnal Program Studi Pendidikan Matematika, 2019
The focus of the current study is to investigate mathematical reasoning and behaviour among a local Indonesian tribe (Sasakese tribe in Lombok) in measurement tradition and their potential integration into mathematics instructions.

FPT-Algorithms for Computing Gromov-Hausdorff and Interleaving Distances Between Trees [PDF]

open access: yes, 2019
The Gromov-Hausdorff distance is a natural way to measure the distortion between two metric spaces. However, there has been only limited algorithmic development to compute or approximate this distance.

From Mechanical Ventilation to Intensive Care Medicine: A Challenge for Bosnia and Herzegovina

open access: yesBiomolecules & Biomedicine, 2009
Intensive care medicine is a relatively new specialty, which was created in the 1950's, after invent of mechanical ventilation, which allowed caring for critically ill patients who otherwise would have died.

Critical review of the levelised cost of energy metric

open access: yesSouth African Journal of Industrial Engineering, 2016
The purpose of this paper is to critically review the ‘levelised cost of energy’ metric used in electricity project development. This metric is widely used, because it is a simple metric to calculate the cost per unit of electricity for a given ...
