RésumeA pair formed by a triangulated category and an autoequivalence is called a categorical dynamical system. Its complexity is measured by the so-called categorical entropy. In this talk, I will present a computation of the categorical entropies of categorical dynamical systems obtained by lifting a sign-stable mutation loop of a quiver to an autoequivalence of the derived category of the corresponding Ginzburg dg algebra. The notion of sign-stability is introduced as a generalization of the pseudo-Anosov property of mapping classes of surfaces. If time permits, we will discuss the pseudo-Anosovness of the autoequivalences constructed.
