Resolve Composition Operators On Function Spaces

In this paper we investigate composition operator C_φfrom B_log^αto Q_K on the unit D of the complex plane. The spaces we consider here contain B_log^αand Q_K. The space B_log^α, which consists of all analytic functions f on D such thatThe spaces Q_K, which consist of all analytic functions on D such thatwe will give the sufficient and nonboundedness and compactness of C_φfrom B_log^αto Q_K.
