Using morphism computations for factoring and decomposing linear functional systems

In particular, we show how the combination of effective methods of computer algebra − based on Gröbner basis techniques over a class of noncommutative polynomial rings of

L’archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des

We show that the topological duals A 0 of these operator rings with the canonical action of A on A 0 furnish strong elimination and duality properties for A A 0 -behaviors and

The general theory is applied to differential-difference systems over Lie groups..

In this paper we associate to a linear differential equation with coefficients in the field of Laurent formal power series a new geometric object, a spectrum in the sense of

Quantification of Iba1 + CD68 + cells (tissue macrophage/microglia activation) in retinas showed more than a twofold increase in right and left eyes compared to naïve eyes (Fig..

In previous contributions I have presented a unified theory of particles and field, in the Geometry of General Relativity, which accounts for all the known force fields, as well as
