In this paper, the Gevrey class regularity of a semigroup associated with a nonlinear Korteweg-de Vries (KdV) equation is considered. By estimating the resolvent of the corresponding linear operator, it can be concluded that thesemigroup generated by the linear operator is not analytic but of Gevrey class $deltain(3/2,infty)$ for $t>0$.
Keywords:Applied Mathematics; Korteweg-de Vries equation; resolvent estimation; analytic semigroup; Gevrey class
