On the Dynamics of Aeolian Sand Ripples

open access: yesMilan Journal of Mathematics, 2023
AbstractThe dynamics of aeolian sand ripples is described by a 1D non-linear evolutive fourth order equation. In this paper, we prove the well-posedness of the classical solutions of the Cauchy problem, associated with this equation.
