A Remark on the Leray's Problem on Stationary Navier-Stokes Flows with   Large Fluxes in Infinite Cylindrical Domains
  We consider Leray's problem on stationary Navier-Stokes flows with arbitrary large fluxes in an unbounded cylinder with several exits to infinity. For a stationary Navier-Stokes flow with large fluxes in the unbounded cylinder we prove that, if the difference between the pressure of the main flow and the pressure of the Poiseuille flow with the same flux in a branch of the cylinder satisfies some asymptotic boundedness condition at $|x|\rightarrow \infty$ then the flow behaves at infinity of the branch like the Poiseuille flow.
