Abstract:The present paper shows that the algebra Image generated by {Cphi|phi set membership, variant Aut(Bn)} is cyclic on H2(Bn), and any nonconstant function f set membership, variant H2(Bn) is a cyclic vector of Image. In addition, the hypercyclic and cyclic composition operators will be discussed.
Keywords:composition operator   algebra   cyclic vector   hypercyclic vector
