Interpolating sequences and the Toeplitz corona theorem on the symmetrized bidisk
Tirthankar Bhattacharyya, Haripada Sau
This paper is a continuation of work done in \cite{BS}. It contains two new theorems about bounded holomorphic functions on the symmetrized bidisk -- a characterization of interpol…
