In this talk, we will give a negative answer to the Hilbert-Schmidt norm boundedness problem for rank one polynomial submodules in Hardy space over the bidisk. Moreover, we find that there is a close connection between the Hilbert-Schmidt norm estimates for homogeneous polynomial submodules and the Fisher-Hartwig conjecture, which describes the asymptotic behavior of Toeplitz determinants for a class of functions.
