Query: Shift invariance and reflexivity of compressions of multiplication
  operators   The property of being shift invariant and being reflexive or transitive in
the case of the space of (asymmetric) truncated Toeplitz operators, and the
space of (asymmetric) dual truncated operators is investigated. Most of the
results obtained are new even for the symmetric case. A characterization of
asymmetric dual truncated Toeplitz operators is also given.
