Solving Differential Equations by Parallel Laplace Method with Assured Accuracy

Malaschonok, Natasha (2007)

Serdica Journal of Computing

The paper has been presented at the 12th International Conference on Applications of Computer Algebra, Varna, Bulgaria, June, 2006We produce a parallel algorithm realizing the Laplace transform method for the symbolic solving of differential equations. In this paper we consider systems of ordinary linear differential equations with constant coefficients, nonzero initial conditions and right-hand parts reduced to sums of exponents with polynomial coefficients.

Some relations satisfied by Hermite-Hermite matrix polynomials

Ayman Shehata, Lalit Mohan Upadhyaya (2017)

Mathematica Bohemica

The classical Hermite-Hermite matrix polynomials for commutative matrices were first studied by Metwally et al. (2008). Our goal is to derive their basic properties including the orthogonality properties and Rodrigues formula. Furthermore, we define a new polynomial associated with the Hermite-Hermite matrix polynomials and establish the matrix differential equation associated with these polynomials. We give the addition theorems, multiplication theorems and summation formula for the Hermite-Hermite...

Sur le théorème de comparaison entre cohomologies de De Rham algébrique et p -adique rigide

Bruno Chiarellotto (1988)

Annales de l'institut Fourier

Soit un fibré vectoriel à connexion sur une courbe algébrique lisse définie sur le corps de nombres algébriques. On démontre qu’il y a équivalence entre le théorème de Clark sur la convergence de séries formelles solutions d’une équation différentielle d’exposants nombres non-Liouville et l’isomorphisme entre la cohomologie de de Rham algébrique du fibré et la cohomologie de de Rham du fibré p -adique associé sur la courbe p -adique rigide associée.
