Abstract
In this article, we consider the incompressible Navier-Stokes equations with linearly growing initial data \(U_0 := u_0(x)-Mx\).
Here \(M\) is an \(n \times n\) matrix, \(trM = 0, M^2\) is symmetric and \(u_0 \in L^{2}(\mathbb{R}^{n}) \cap L^{n}(\mathbb{R}^{n})\). Under these conditions, we consider
\(v(t) := u(t) - e^{-tA}u_0\), where \(u(x) := U(x) - Mx\) and \(U(x)\) is the mild solution of the incompressible Navier-Stokes equations
with linearly growing initial data. We shall show that \(D^\beta v(t)\) on the \(L^{2}(\mathbb{R}^{n})\) norm like \(t^{\frac{-|\beta|-1}{2}-\frac{n}{4}}\) for all \(|\beta|\geq 0\).
