Norms of Toeplitz and Hankel Operators on Hardy Type Subspaces of Rearrangement-Invariant Spaces

摘要

We prove analogues of the Brown-Halmos and Nehari theorems on the norms of Toeplitz and Hankel operators, respectively, acting on subspaces of Hardy type of reflexive rearrangement-invariant spaces with nontrivial Boyd indices.
