La méthode de Cholesky
L’objet de cet article est de présenter le manuscrit original, jusqu’alors inconnu, de Cholesky où il explique sa méthode de résolution des systèmes d’équations linéaires. Le contexte historique est précisé après une brève biographie. La méthode des moindres carrés et son application à la topographie, ainsi que les diverses méthodes directes de résolution des systèmes linéaires sont discutées. Ensuite, la diffusion de la méthode de Cholesky est retracée et l’on donne une analyse détaillée du manuscrit...

Lanczos-like algorithm for the time-ordered exponential: The -inverse problem
The time-ordered exponential of a time-dependent matrix is defined as the function of that solves the first-order system of coupled linear differential equations with non-constant coefficients encoded in . The authors have recently proposed the first Lanczos-like algorithm capable of evaluating this function. This algorithm relies on inverses of time-dependent functions with respect to a non-commutative convolution-like product, denoted by . Yet, the existence of such inverses, crucial to...
