Let $[b,\mathcal T_\alpha]~(0\leq\alpha< n) $ be the commutators generated by $ BMO
(\mathbb R^ n) $ functions and a class of sublinear operators satisfying certain size
conditions. The aim of this paper is to study the endpoint estimates of these commutators in
the weighted Morrey spaces and in the generalized Morrey spaces, under the assumptions

Let be the commutators generated by functions and a class of sublinear operators satisfying certain size conditions. The aim of this paper is to study the endpoint estimates of these commutators in the weighted Morrey spaces and in the generalized Morrey spaces, under the assumptions that satisfy (weighted or unweighted) endpoint inequalities on and on bounded domains. Furthermore, as applications of our main results, we will obtain, in the endpoint case, the boundedness properties of many important operators in classical harmonic analysis on the weighted Morrey and the generalized Morrey spaces.
