The Generalized Lasso Problem and Uniqueness [PDF]

open access: yesElectronic Journal of Statistics, 2018
We study uniqueness in the generalized lasso problem, where the penalty is the $\ell_1$ norm of a matrix $D$ times the coefficient vector. We derive a broad result on uniqueness that places weak assumptions on the predictor matrix $X$ and penalty matrix $

Uniqueness of limit cycles for quadratic vector fields [PDF]

open access: yes, 2019
Producción CientíficaThis article deals with the study of the number of limit cycles surrounding a critical point of a quadratic planar vector field, which, in normal form, can be written as x ′ = a1x − y − a3x 2 + (2a2 + a5)xy+a6y 2 , y ′ = x ...

Amenability and uniqueness

open access: yesAdvances in Mathematics, 2013
The main result of this paper is a characterization of properly infinite injective von Neumann algebras and of nuclear C*-algebras by using a uniqueness theorem, based on generalizations of Voiculescu's famous Weyl-von Neumann theorem.

Unique extremality [PDF]

open access: yesJournal d'Analyse Mathématique, 1998
Let \(R\) be a Riemann surface and \(T(R)\) be the Teichmüller space of \(R\), viewed as the Teichmüller equivalence classes of Beltrami coefficients. The following theorems are proved in this paper: A Beltrami coefficient \(\mu\) is uniquely extremal in its Teichmüller class if, and only if, it is uniquely extremal in its infinitesimal Teichmüller ...

The gut microbiome of healthy Japanese and its microbial and functional uniqueness

open access: yesDNA Research, 2016
The human gut microbiome has profound influences on the host's health largely through its interference with various intestinal functions. As recent studies have suggested diversity in the human gut microbiome among human populations, it will be ...

Weak-Strong Uniqueness in Fluid Dynamics [PDF]

open access: yesPartial Differential Equations in Fluid Mechanics, 2017
We give a survey of recent results on weak-strong uniqueness for compressible and incompressible Euler and Navier-Stokes equations, and also make some new observations.

GR uniqueness and deformations [PDF]

open access: yes, 2015
In the metric formulation gravitons are described with the parity symmetric $S_+^2\otimes S_-^2$ representation of Lorentz group. General Relativity is then the unique theory of interacting gravitons with second order field equations.

The uniqueness of the rational Bézier polygon is unique

open access: yesComputer Aided Geometric Design, 2022
Given a properly parameterized rational Bézier curve of irreducible degree, it is well-known that its control polygon is uniquely defined. We prove that this property is peculiar to the Bézier model. In the rational form associated with any other normalized polynomial basis, Moebius reparameterizations change the control polygon, so the same segment ...
