Abstract

In this paper, we present infinitely many conserved densities satisfying particular conservation law Ft=(2uF)xF_{t}=(2uF)_{x} for the generalized Riemann equations at N=2,3,4N=2,3,4. In the N=2N=2 case, we also construct conserved densities corresponding to new conservation laws containing an arbitrary smooth function. In virtue of reductions and/or changes of variables, related conserved densities are obtained for two component Hunter-Saxton equation, Hunter-Saxton equation, Gurevich-Zybin equation and Monge-Ampere equation.
