; Immanuel Van SantenAbstractWe study the possible dynamical degrees of automorphisms of the affine space$\mathbb {A}^n$. In dimension$n=3$, we determine all dynamical degrees arising from the composition of an affine automorphism with a triangular one. This generalizes the easier case of shift-like automorphisms which can be studied in any dimension. We also prove that each weak Perron number is the dynamical degree of an affine-triangular automorphism of the affine space$\mathbb {A}^n$for somen, and we give the best possiblenfor quadratic integers, which is either$3$or$4$.
