In this note, we present an abstract approach for the study of a second-order boundary-value problem on cusp domain. This study is performed in the framework of anisotropic little Holder spaces. Our strategy is to use of the commutative version of the well known sums of operators theory. This technique allows us to obtain the space regularity of the unique strict solution for our problem.
