Efficient numerical integration for N th-order non-autonomous linear differential equations

Bader, Philipp Karl Heinz; Blanes Zamora, Sergio; Casas, Fernando; Ponsoda Miralles, Enrique (Elsevier, 2016-01-01)

We consider the numerical integration of high-order linear non-homogeneous differential equations, written as first order homogeneous linear equations, and using exponential methods. Integrators like Magnus expansions ...
Exponential integrators for coupled self-adjoint non-autonomous partial differential systems

Ponsoda Miralles, Enrique; Blanes Zamora, Sergio (Elsevier, 2014-09)

We consider the numerical integration of coupled self-adjoint non-autonomous partial differential systems. Under convergence conditions, the solution can be written as a series expansion where each of its terms correspond ...
Magnus integrators for solving linear-quadratic differential games

Blanes Zamora, Sergio; Ponsoda Miralles, Enrique (Elsevier, 2012-08)

We consider Magnus integrators to solve linear-quadratic N-player differential games. These problems require to solve, backward in time, non-autonomous matrix Riccati differential equations which are coupled with the ...
New efficient numerical methods to describe the heat transfer in a solid medium

Ponsoda Miralles, Enrique; Blanes Zamora, Sergio; Bader, Philipp (Elsevier, 2011-10)

The analysis of heat conduction through a solid with heat generation leads to a linear matrix differential equation with separated boundary conditions. We present a symmetric second order exponential integrator for the ...
Nuevos planteamientos en las prácticas de matemáticas con Mathematica en la ETSICCP de Valencia

Company Rossi, Rafael; García Raffi, Luis Miguel; Pérez Peñalver, María José; Ponsoda Miralles, Enrique; Rodríguez López, Jesús; Romero Vivó, Sergio; Tirado Peláez, Pedro (Instituto de Ciencias de la Educación de la Universidad de Alicante, 2011-11-08)

[ES] En el contexto de los nuevos planes de estudio, los profesores del departamento de Matemática Aplicada de la ETSICCP de Valencia nos planteamos cómo enfocar las prácticas de informática de las dos asignaturas de primer ...
Soluciones numericas continuas de ecuaciones diferenciales matriciales con cotas de error a priori

Ponsoda Miralles, Enrique (Universitat Politècnica de València, 2009-06-03)

EN ESTA MEMORIA SE CONSIDERAN DOS TIPOS DE ECUACIONES DIFERENCIALES MATRICIALES. EN PRIMER LUGAR SE CONSTRUYEN SOLUCIONES NUMERICAS PARA PROBLEMAS DE VALORES INICIALES MATRICIALES UTILIZANDO METODOS LINEALES MULTIPASO ...
Structure preserving integrators for solving (non-)linear quadratic optimal control problems with applications to describe the flight of a quadrotor

Bader, Philipp; Blanes Zamora, Sergio; Ponsoda Miralles, Enrique (Elsevier, 2014-05-15)

[EN] We present structure preserving integrators for solving linear quadratic optimal control problems. The goal is to build methods which can also be used for the integration of nonlinear problems if they are previously ...
Symplectic integrators for second-order linear non-autonomous equations

Bader, Philipp; Blanes Zamora, Sergio; Casas, Fernando; Kopylov, Nikita; Ponsoda Miralles, Enrique (Elsevier, 2018)

[EN] Two families of symplectic methods specially designed for second-order time-dependent linear systems are presented. Both are obtained from the Magnus expansion of the corresponding first-order equation, but otherwise ...
Symplectic integrators for the matrix Hill equation

Bader, Philipp; Blanes Zamora, Sergio; Ponsoda Miralles, Enrique; Seydaoglu, Muaz (Elsevier, 2017)

[EN] We consider the numerical integration of the matrix Hill equation. Parametric resonances can appear and this property is of great interest in many different physical applications. Usually, Hill s equations originate ...
Time-averaging and exponential integrators for non-homogeneous linear IVPs and BVPs

Blanes Zamora, Sergio; Ponsoda Miralles, Enrique (Elsevier, 2012-08)

We consider time-averaging methods based on the Magnus series expansion jointly with exponential integrators for the numerical integration of general linear non-homogeneous differential equations. The schemes can be ...
