Query: Isomorphisms of Non-Commutative Domain Algebras   Noncommutative domain algebras were introduced by Popescu as the
non-selfadjoint operator algebras generated by weighted shifts on the Full Fock
space. This paper uses results from several complex variables to classify many
noncommutative domain algebras, and it uses results from operator theory to
obtain new bounded domains in hermitian spaces with non-compact automorphic
group.
