Sumario:[EN]The aim of this work is to offer a method for studying the consis tence and computing the set of solutions of some infinite systems of differential equations from the exponential map of a finite potent endomorphism. This method is related with the Drazin inverse of a finite potent operator on an infinite-dimensional vector space that was introduced by the author in 2019. Moreover, explicit examples of the exponential of a finite potent endomorphism and the set of solutions of an infinite system of differential equations are provided.
