Sulfur-bearing molecules in a sample of early star-forming cores
N. C. Martinez, S. Paron, M. E. Ortega +5
The sulfur content in dense molecular regions of the interstellar medium is highly depleted in comparison to diffuse clouds. The reason of this phenomenon is unclear, thus it is ne…
Nonintegrability of the unfoldings of codimension-two bifurcations
Primitivo B. Acosta-Humánez, Kazuyuki Yagasaki
Codimension-two bifurcations are fundamental and interesting phenomena in dynamical systems. Fold-Hopf and double-Hopf bifurcations are the most important among them. We study the…
Liouvillian Solutions of Schrödinger Equation with Polynomial Potentials using Gröbner Basis
Primitivo Belén Acosta-Humánez, Henock Venegas-Gómez
The main aim of this paper is the presentation of a new methodology to obtain Liouvillian solutions of stationary one dimensional Schrödinger equation with quasi-solvable polynomia…
Generalized Lennard-Jones Potentials, SUSYQM and Differential Galois Theory
Manuel F. Acosta-Humánez, Primitivo B. Acosta-Humánez, Erick Tuirán
In this paper we start with proving that the Schrödinger equation (SE) with the classical Lennard-Jones (L-J) potential is nonintegrable in the sense of the differential Gal…
Variations for Some Painlevé Equations
Primitivo B. Acosta-Humánez, Marius van der Put, Jaap Top
This paper first discusses irreducibility of a Painlevé equation . We explain how the Painlevé property is helpful for the computation of special classical and algebraic solutio…
