[Asymptotique du multiplicateur de Floquet de plus grand module pour les matrices coopératives]
Annales de la Faculté des sciences de Toulouse : Mathématiques, Série 6, Tome 31 (2022) no. 4, pp. 1213-1221.

Le but de cet article est d’établir un lien entre le rayon spectral de la matrice de monodromie d’une équation différentielle linéaire à coefficients périodiques dx dt(t)=A(t)x(t), avec A(t) une matrice coopérative irréductible, avec la moyenne de l’abcisse spectrale 0 1 s(A(u))du.

The aim of this note is to give a link between the spectral radius of the monodromy matrix of a linear differential equation with periodic coefficients dx dt(t)=A(t)x(t), with A(t) a cooperative irreducible matrix, and the mean spectral abscissa 0 1 s(A(u))du.
