DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GDEq/51/">Th
 e Euler system on a space curve</a>\nby Anna Duyunova and Sergey Tychkov a
 s part of Geometry of differential equations seminar\n\n\nAbstract\nWe con
 sider flows of an inviscid medium on a space curve in a constant gravitati
 onal field (the Euler system). We discuss symmetries and differential inva
 riants of the Euler system\, and give their classification based on symmet
 ries group of the system. Using differential invariants for this system\, 
 we obtain its quotient. The solutions of the quotient equation that are co
 nstant along characteristic vector field provide some solutions of the Eul
 er system.\n\nJoint work with Valentin Lychagin.\n
