چکیده
We show that the solutions to the non-stationary Navier–Stokes equations in R (d = 2, 3) which are left invariant under the action of discrete subgroups of the orthogonal group O(d) decay much faster as |x| → ∞ or t → ∞ than in generic case and we compute, for each subgroup, the precise decay rates in space-time of the velocity field.

Viscous potential flow
Potential flows u = ∇φ are solutions of the Navier–Stokes equations for viscous incompressible fluids for which the vorticity is identically zero. The viscous term μ∇u = μ∇∇φ vanishes, but the viscous contribution to the stress in an incompressible fluid (Stokes 1850) does not vanish in general. Here, we show how the viscosity of a viscous fluid in potential flow away from the boundary layers e...
متن کاملOn L 1 - Stability of Stationary Navier - Stokes Flows in
Stability of stationary Navier-Stokes flows in , n ≥ 3, is discussed in the function space L or H (Hardy space). It is shown that a stationary flow w is stable in H (resp. L) if sup |x| · |w(x)| + sup |x|2|∇w(x)| (resp. ‖w‖(n,1) + ‖∇w‖(n/2,1)) is small. Explicit decay rates of the form O(t−β/2), 0 < β ≤ 1, are deduced for perturbations under additional assumptions on w and on initial data. The ...
متن کاملThe Navier-Stokes equations for the motion of compressible, viscous fluid flows with the no-slip boundary condition
The Navier-Stokes equations for the motion of compressible, viscous fluids in the half-space R+ with the no-slip boundary condition are studied. Given a constant equilibrium state (ρ̄, 0), we construct a global in time, regular weak solution, provided that the initial data ρ0,u0 are close to the equilibrium state when measured by the norm |ρ0 − ρ̄|L∞ + |u0|H1 and discontinuities of ρ0 decay near ...
متن کاملNavier - Stokes Space Time Decay Revisited
In this paper we analyze the decay in space and time of strong solutions to the Navier-Stokes equations is n space dimensions. We give first a brief review of known results, focusing on some of the Miyakawa techniques, which are then extended to cover the decay for higher derivatives. ∗
متن کاملPersistence of Invariant Manifolds for Nonlinear PDEs
We prove that under certain stability and smoothing properties of the semi-groups generated by the partial differential equations that we consider, manifolds left invariant by these flows persist under C perturbation. In particular, we extend well known finite-dimensional results to the setting of an infinite-dimensional Hilbert manifold with a semi-group that leaves a submanifold invariant. We...
