报告摘要:In this talk, we first briefly recall some well-known results related to the classic Camassa-Holm (CH) equation and the generalized CH-type equations. Especially, we shall consider the non-isospectral two-component CH system (2NSQQ) in Besov spaces. It is shown that the global well-posedness of the strong solutions to the 2NSQQ system can be determined by the time-dependent parameters of the system without sign condition on initial momentum, which is different with the classical ones for isospectral CH-type equations.
