Abstract:

In this paper, we study the product operators of Volterra operator V and Toeplitz operator Tφ on the classical Hardy space Lφ=TφV and Rφ=VTφ, and we obtain some basic properties of Lφ and Rφ, we also get a result of Lφ which is similar to the Coburn theorem of Toeplitz operator. The necessary and sufficient conditions for V and Tφ to be commutative are given in this paper, and the symbol of Lφ and Rφ is characterized when zjH2 (j=1,2,) are the common invariant subspaces of Lφ and Rφ.

Key words: Volterra operator, Toeplitz operator, Coburn theorem, Commutative, Invariant subspace
