Abstract

Let-----. For an analytic self-map---of---, Let---be the composition operator with composite map---so that----. Let---be a bounded analytic function on---. The weighted composition operator---is defined by---. Suppose that---is the Hardy space, consisting of all analytic functions defined on---, whose Maclaurin cofficients are square summable. . . . . .
