Generalized α-Attractor Models from Elementary Hyperbolic Surfaces

Advances in Mathematical Physics, 2018
We consider generalized α-attractor models whose scalar potentials are globally well-behaved and whose scalar manifolds are elementary hyperbolic surfaces.

Large amplitude oscillations for a class of symmetric polynomial differential systems in R³

Anais da Academia Brasileira de Ciências, 2007
In this paper we study a class of symmetric polynomial differential systems in R³, which has a set of parallel invariant straight lines, forming degenerate heteroclinic cycles, which have their two singular endpoints at infinity.

Global configurations of singularities for quadratic differential systems with exactly three finite singularities of total multiplicity four

Electronic Journal of Qualitative Theory of Differential Equations, 2015
In this article we obtain the geometric classification of singularities, finite and infinite, for the two subclasses of quadratic differential systems with total finite multiplicity $m_f=4$ possessing exactly three finite singularities, namely: systems ...

Did Perrin's experiments convert Poincaré to Scientific Realism? [PDF]

, 2013
In this paper I argue that Poincaré’s acceptance of the atom does not indicate a shift from instrumentalism to scientific realism. I examine the implications of Poincaré’s acceptance of the existence of the atom for our current understanding of his ...

Global phase portraits of quintic reversible uniform isochronous centers

Electronic Journal of Qualitative Theory of Differential Equations
This paper studies the global phase portraits of uniform isochronous quintic centers at the origin with time reversibility such that their nonlinear part is not homogeneous.

An extension of the poincaré compactification and a geometric interpretation

, 2017
Our purpose in this paper is to understand the geometry of the Poincaré compactification and to apply this technique to prove that there exists a Poincaré compactification of vector fields defined by rational functions and of vector field that are the ...
