Abstract
We classify all tuples of operators in the Cowen-Douglas class of rank 1 and 2 homogeneous with
Mobn using Wilkins' classification of homogeneous hermitian holomorphic vector bundles over bounded symmetric domains. It is also observed that these homogeneous tuples can be realised as the adjoint of the tuples of multiplication operators on the quotient Hilbert modules obtained from certain submodules of the weighted Bergman modules on the open unit polydisc.
