Abstract:

We consider flows of an inviscid medium on a space curve in a constant
gravitational field (the Euler system). We discuss symmetries and
differential invariants of the Euler system, and give their
classification based on symmetries group of the system. Using
differential invariants for this system, we obtain its quotient. The
solutions of the quotient equation that are constant along
characteristic vector field provide some solutions of the Euler system.

Joint work with Valentin Lychagin.
