Abstract:

In this paper, by Kato's theory of semigroup and the definition of the dissipative operator, we study the initial value problem of a modified Camassa-Holm equation with cubic nonlinearity, and establish the existence and uniqueness of its solutions in Sobolev space Hs,p(R), s1, p(1,), which extend the well-posedness of its solutions in Besov space Bsp,r(R) (p, r1, s>max{2+1p,52}) obtained by Fu et al. (J Differ Equations, 2013, 255: 1905-1938).

Key words: The modified Camassa-Holm equation, Well-posedness, Dissipative operator, Kato's theory of semigroup
