We make several remarks on the B-JIMWLK hierarchy. First, we present a simpleand instructive derivation of this equation by considering an arbitraryprojectile wave function with small number of valence gluons. We alsogeneralize the equation by including corrections which incorporate effects ofhigh density in the projectile wave function. Second, we systematically derivethe dipole model approximation to the hierarchy. We show that in the dipoleapproximation the hierarchy has a simplifying property that allows its solutionby solving the classical equation followed by averaging over the ensemble ofinitial conditions.Comment: 8 pages, references added.
