A necessary and sufficient condition for the acting of F from a space lp1 (P1 ? 1) into another lp2(p2 ? 1) is also established.en10.1080/10236190412331317139info:eu-repo/semantics/closedAccessComposition operatorContinuous and bounded nonlinear operatorsDiscrete semi-axisNemytskii operatorArticle1112127Q3
