Quasiconformal maps on non-rigid Carnot groups [PDF]

arXiv, 2013
We study quasiconformal maps on non-rigid Carnot groups equipped with Carnot metric. We show that for most non-rigid Carnot groups N, all quasiconformal maps on N must be biLipschitz.

On the smoothness of $C^1$-contact maps in $C^{\infty}$-rigid Carnot groups [PDF]

arXiv, 2020
We show that in any $C^\infty$-rigid Carnot group in the sense of Ottazzi - Warhurst, $C^1$-contact maps are automatically smooth.

Testing the Bonds: Franco‐Russian Alliance and the First Sino‐Japanese War

Australian Journal of Politics &History, EarlyView.
The conclusion of the Franco‐Russian Alliance was one of the major turning points in the history of international relations before the outbreak of the First World War in 1914. However, the alliance was put under its first severe test only months after its ratification in 1894.

Operational definition of developmental and epileptic encephalopathies to underpin the design of therapeutic trials

Epilepsia, EarlyView.
Abstract Developmental and epileptic encephalopathies (DEEs) are the most severe group of epilepsies, characterized by drug‐resistant seizures and developmental slowing or regression. DEEs encompass many epilepsy syndromes, although not all patients with a DEE can be classified into a specific syndrome.

Compression bounds for Lipschitz maps from the Heisenberg group to $L_1$ [PDF]

, 2009
We prove a quantitative bi-Lipschitz nonembedding theorem for the Heisenberg group with its Carnot-Carath\'eodory metric and apply it to give a lower bound on the integrality gap of the Goemans-Linial semidefinite relaxation of the Sparsest Cut ...

Global contact and quasiconformal mappings of Carnot groups [PDF]

arXiv, 2014
We show that globally defined quasiconformal mappings of rigid Carnot groups are affine, but that globally defined contact mappings of rigid Carnot groups need not be quasiconformal, and a fortiori not affine.

Metric currents, differentiable structures, and Carnot groups [PDF]

, 2011
We examine the theory of metric currents of Ambrosio and Kirchheim in the setting of spaces admitting differentiable structures in the sense of Cheeger and Keith.

Minimal surfaces in the Heisenberg group

, 2006
We investigate the minimal surface problem in the three dimensional Heisenberg group, H, equipped with its standard Carnot-Caratheodory metric. Using a particular surface measure, we characterize minimal surfaces in terms of a sub-elliptic partial ...
