Abstract
We introduce the notions of Fatou and Julia sets in the context of word maps on complex Lie groups and polynomial maps on finite-dimensional associative -algebras. For the group-theoretic question, we investigate the dynamics of the power map on the Lie group , where is an integer. For the algebra-related question, we study polynomial self-maps of induced by monic polynomials in one variable. In both cases, we pin down the explicit description of the Fatou and Julia sets. We also show that there does not exist any wandering Fatou component of the pair where is a monic polynomial of degree .
