Generalization of Zernike polynomials for regular portions of circles and ellipses
Navarro, Rafael; López García, José Luis
; Díaz, José A.; Pérez Sinusía, Ester (Optical Society of America, 2014)
Artículo / Artikulua 
Zernike polynomials are commonly used to represent the wavefront phase on circular optical apertures, since they form a complete and orthonormal basis on the unit circle. Here, we present a generalization of this Zernike ... -
Hill problem analytical theory to the order four: application to the computation of frozen orbits around planetary satellites
Lara, Martín; Palacián Subiela, Jesús Francisco (Hindawi Publishing Corporation, 2009)
Artículo / Artikulua
Frozen orbits of the Hill problem are determined in the double-averaged problem, where short and long-period terms are removed by means of Lie transforms. Due to the perturbation method we use, the initial conditions ... -

A mixed-FEM and BEM coupling for the approximation of the scattering of thermal waves in locally non-homogeneous media
Rapún Araiz, María Luisa; Sayas, Francisco Javier (EDP Sciences, 2006)
Artículo / Artikulua
This paper proposes and analyzes a BEM-FEM scheme to approximate a time-harmonic diffusion problem in the plane with non-constant coefficients in a bounded area. The model is set as a Helmholtz transmission problem with ... -
Modified Douglas splitting methods for reaction–diffusion equations

New asymptotic expansion and error bound for Stirling formula of reciprocal Gamma function
Pagola Martínez, Pedro Jesús (Ele-Math, 2018)
Artículo / Artikulua
Studying the problem about if certain probability measures are determinate by its moments [4, 8, 10] is useful to know the asymptotic behavior of the probability densities for large values of argument. This requires, ... -
New series expansions of the 3F2 function
López García, José Luis ; Pagola Martínez, Pedro Jesús ; Pérez Sinusía, Ester (2015)
Artículo / Artikulua
We can use the power series definition of 3F2(a1, a2, a3; b1, b2; z) to compute this function for z in the unit disk only. In this paper we obtain new expansions of this function that are convergent in larger domains. ... -
