Conjugations in $L^2$ and their invariants
TL;DR: Conjugations in space L 2 of the unit circle commuting with multiplication by $z$ or intertwining multiplications by$z$ and $\bar z$ are characterized in this article.

Characterizations of Asymmetric Truncated Toeplitz and Hankel Operators
TL;DR: In this paper, it was shown that asymmetric truncated Toeplitz operators can be characterized in terms of compressed shifts and rank-two operators of special form, and that such characterizations hold in all cases.
Matrix representations of truncated Toeplitz operators
TL;DR: In this article, the authors describe matrix representations of truncated Toeplitz operators on the model space K B, where B is an infinite Blaschke product satisfying some additional conditions.

TL;DR: In this paper, the authors considered asymmetric truncated Toeplitz operators acting between two finite-dimensional model spaces and computed the dimension of the space of all such operators.
