Abstract
Abstract In this paper, we consider a hyperbolic perturbation of the 2D Navier–Stokes equations, which consists in adding the term ε u t t {\varepsilon u_{tt}} to the Navier–Stokes equations. We prove the global persistence of analyticity and Gevrey-class of solutions. Moreover, we prove that the solution to the perturbed Navier–Stokes equations approximates the solution to the classical Navier–Stokes equations.
