On existence of general solution of the Navier-Stokes equations for 3D non-stationary incompressible flow
Sergey V. Ershkov
A new presentation of general solution of Navier-Stokes equations is considered here. We consider equations of motion for 3-dimensional non-stationary incompressible flow. The fiel…
