Abstract

This work is a continuation of [13]. We study the linear disjointness between higher-order oscillating sequences and nonlinear dynamical systems. Specifically, we prove that any oscillating sequence of order m=d+k-1 and any simple polynomial skew product of degree k on the d-Euclidean space are linearly disjoint. Additionally, we demonstrate that any oscillating sequence of order d and any minimal mean attractable and minimal quasi-discrete spectrum dynamical system of order d are linearly disjoint. Finally, we introduce multi-linearly disjoint sequences and construct examples of such sequences.
