The regularity of the $\overline{\partial }$ -problem on the domain $\{\left|{z_1}\right|\!<\!\left|{z_2}\right|\!<\!1\}$ in $\mathbb C ^2$ is studied using $L^2$ -methods. Estimates are obtained for the canonical solution in weighted $L^2$ -Sobolev spaces with a weight that is singular at the point $(0,0)$ . In particular, the singularity of the Bergman projection for the Hartogs triangle is contained at the singular point and it does not propagate.
