摘 要: | 1 Introduction and Preliminaries In thiS paper,we are interested in one dimensional viscous Camassa-Holm equatin u_t-u_(xxt)-γ(u_(xx)-u_(xxxx))+3uu_x=uu_(xxx)+2u_xu_(xx)+f(x,t),x∈Ω,t>0,(1)where Ω=0,L],γ>0 is the constant viscosity and the forcing term f is ω-periodic in time t.We shall prove that under a periodic boundary condition
