On démontre l'existence et l'unicité pour un problème elliptique semilinéaire avec mémoire, dans l'arrangement faible et classique. Ce problème décrit le comportement effective d'un tissu biologique sous l'injection d'un courant électrique dans le domaine des radiofréquences.

We prove the existence and uniqueness for a semilinear elliptic problem with memory, both in the weak and the classical setting. This problem describes the effective behaviour of a biological tissue under the injection of an electrical current in the radiofrequency range.
