Abstract
Rigged modules over an operator algebra are a generalization of Hilbert modules over a C^{*}algebra. We characterize the rigged modules over an operator algebra A which are orthogonally complemented in
C_{∞}(A), the space of infinite columns with entries in A. We show that every such rigged module 'restricts' to a bimodule of Morita equivalence between appropriate stably isomorphic operator algebras.
