Pointwise Multipliers between weighted Copson and Cesàro function spaces (1902.07604v1)

Abstract: In this paper the solution of the pointwise multiplier problem between weighted Copson function spaces $\operatorname{Cop}{p_1,q_1}(u_1,v_1)$ and weighted Ces`{a}ro function spaces $\operatorname{Ces}{p_2,q_2}(u_2,v_2)$ is presented, where $p_1,\,p_2,\,q_1,\,q_2 \in (0,\infty)$, $p_2 \le q_2$ and $u_1,\,u_2,\,v_1,\,v_2$ are weights on $(0,\infty)$.
