Query: Characterizations of asymmetric truncated Toeplitz operators   The aim of this paper is to investigate asymmetric truncated Toeplitz
operators with $L^2$ symbols between two different model spaces given by inner
functions such that one divides the other. Characterizations of these operators
are given in terms of rank two operators. A description of the class of symbols
for which the corresponding asymmetric truncated Toeplitz operator is equal to
the zero operator is also given.
