Abstract
The linear dynamics of ion sputtered solids is essential to understanding the evolution of
ordered and disordered surface patterns. We review the existing models of linear dynamics and
point out qualitative discrepancies between theory and experimental observations that
characterize the linear regime. In particular, we emphasize the importance of experimental and
theoretical analysis of bifurcation points: certain values of control parameters such as ion beam
