摘要

A system of linearized equations of the (1+1)-dimensional Sine-Gordon (SG) equation and its B?cklund transformation are given to determine not only nonlocal symmetries but also nonlocal conservation laws of the SG equation. Through the parameter expansion procedure, a sequence of infinitely many nonlocal symmetries and a sequence of infinitely many nonlocal conservation laws are obtained.
