Title: Symmetries of hydrodynamic equations and thermodynamics
The talk discusses two-dimensional hydrodynamics equations, the Euler equation and the Navier-Stokes equation. Using the symmetry algebra of these equation we study various classes of thermodynamic relations between density, pressure, temperature, and entropy that are invariant with respect to the symmetry action.
