In the present paper, we study a mixed problem with only integral conditions for a class second order parabolic equations. We prove the existence and uniqueness of the solution. The proof is based on two sided a priori estimates and on the density of the range of the operator generated by the studied problem.Dans le présent travail, on étudie un problème mixte avec uniquement des conditions intégrales pour une classe d'équations paraboliques du second ordre. On montre l'existence et l'unicité de la solution. La démonstration est basée sur deux estimations a priori et sur la densité de l'ensemble des images de l'opérateur engendré par le problème étudié.Mesloub Saïd, Bouziani Abdelfatah.
