Abstract: In this paper, we study the generalized Camassa-Holm equation with (k+1)-degree nonlinearities. By use of moderate weight functions, we prove some persistence results for the solution to the equation in weighted Lp spaces. We also establish the asymptotic profiles of the solution as" x→+∞ and x→-∞.

Keywords: generalized Camassa-Holm equations; persistence properties; weighted spaces
