Symmetries and conservation laws of Navier-Stokes equations. (English) Zbl 0682.35086

By direct calculations it is proved that the algebra of all symmetries of Navier-Stokes equations consists only of the contact symmetries. It is also proved that the space of all conservation laws of these equations is generated by a “generalised impulse”, the impulse moment and the quantity of substance conservation laws.
