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 ...

Primate Social Cognition: Uniquely Primate, Uniquely Social, or Just Unique? [PDF]

open access: yesNeuron, 2010
Primates undoubtedly have impressive abilities in perceiving, recognizing, manipulating, and predicting other individuals, but only great apes seem to recognize the cognitive basis of manipulative and cooperative tactics or the concept of self. None of these abilities is unique to primates.

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.

Solutions of fractional nabla difference equations - existence and uniqueness [PDF]

open access: yesOpuscula Mathematica, 2016
In this article, we discuss existence, uniqueness and dependency of solutions of nonlinear fractional nabla difference equations in a Banach space equipped with a suitable norm, using the contractive mapping approach. As an application of the established

Uniqueness and non-uniqueness in percolation theory

open access: yes, 2005
This paper is an up-to-date introduction to the problem of uniqueness versus non-uniqueness of infinite clusters for percolation on ${\mathbb{Z}}^d$ and, more generally, on transitive graphs.
