| Abstract： |
n this paper, the authors completely characterize when two dual truncated
Toeplitz operators ar e essentially commuting and when the semicommutator of two dual
truncated Toeplitz operators is compact. Their main idea is to study dual truncated
Toeplitz operators via Hankel operators, Toeplitz operators and function algebras. |
