Tautological systems of differential equations are introduced by Lian and Yau in order to describe the differential equations satisfied by the period integrals of hyperplane sections of complex projective homogeneous Calabi-Yau varieties. We introduce the $\ell$-adic tautological systems and study their relation with exponential sums associated to representations of reductive groups.
