Norms of Toeplitz and Hankel Operators on Hardy Type Subspacesof
Rearrangement-Invariant Spaces
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 over the unit circle.
