Improving the approximation of the first and second order statistics of the response stochastic process to the random Legendre differential equation

Calatayud-Gregori, Julia; Cortés, J.-C.; Jornet-Sanz, Marc (Springer-Verlag, 2019-06)

[EN] In this paper, we deal with uncertainty quantification for the random Legendre differential equation, with input coefficient A and initial conditions X-0 and X-1. In a previous study (Calbo et al. in Comput Math Appl ...
Laguerre random differential polynomials: definition, differential and statistical properties

Cortés, J.-C.; Jódar Sánchez, Lucas Antonio; Company Rossi, Rafael; Villafuerte, Laura (University of Manitoba - Department of Computer Science, 2015-11)

[EN] In this paper we introduce the Laguerre polynomials as mean square solutions of random differential equations. The study is based on the construction of an infinite random power series solution which becomes a random ...
Mean Square Analytic Solutions of Random Linear Models

Calbo Sanjuán, Gema (2010-11-02)

El objetivo de este proyecto de tesis doctoral es el desarrollo de técnicas analítico-numéricas para resolver, en media cuadrática problemas, de valores iniciales de ecuaciones y sistemas de ecuaciones en diferencias y ...
Numerical solution of random differential initial value problems: Multistep methods

Cortés, J.-C.; Jódar Sánchez, Lucas Antonio; Villafuerte, L. (Wiley: 12 months, 2011-01)

This paper deals with the construction of numerical methods of random initial value problems. Random linear multistep methods are presented and sufficient conditions for their mean square convergence are established. Main ...
Numerical solution of random differential models

Cortés López, Juan Carlos; Jódar Sánchez, Lucas Antonio; Villafuerte Altuzar, Laura; Company Rossi, Rafael (Elsevier, 2011-10)

This paper deals with the construction of a numerical solution of random initial value problems by means of a random improved Euler method. Conditions for the mean square convergence of the proposed method are established. ...
Random fractional generalized Airy differential equations: A probabilistic analysis using mean square calculus

Burgos-Simon, Clara; Cortés, J.-C.; Debbouche, A.; Villafuerte, L.; Villanueva Micó, Rafael Jacinto (Elsevier, 2019)

[EN] The aim of this paper is to study a generalization of fractional Airy differential equations whose input data (coefficient and initial conditions) are random variables. Under appropriate hypotheses assumed upon the ...
Random Hermite differential equations: Mean square power series solutions and statistical properties

Calbo Sanjuán, Gema; Cortés López, Juan Carlos; Jódar Sánchez, Lucas Antonio (Elsevier, 2011-12-01)

This paper deals with the construction of random power series solution of second order linear differential equations of Hermite containing uncertainty through its coefficients and initial conditions. Under appropriate ...
