Abstract
In this paper, we give a direct proof of \(t^{-1}\) (optimal) linear decay rate for Euler-Coriolis equations in \(L^{\infty }\) space-time. Our proof is based on a proper decomposition of the explicit solution and \(L^{\infty }\) estimate for the kernels, which captures the dispersive mechanism.
