    "abstract": "We give a Lax description for the system of polytropic gas equations. The\nspecial structure of the Lax function naturally leads to the two infinite sets\nof conserved charges associated with this system. We obtain closed form\nexpressions for the conserved charges as well as the generating functions for\nthem. We show how the study of these generating functions can naturally lead to\nthe recursion relation between the conserved quantities as well as the higher\norder Hamiltonian structures.",
