We investigate the extent to which the study of quasimultiplierscan be made beyond Banach algebras. We will focus mainly on the class of -algebras, in particular on complete -normed algebras, 0<≤1, not necessarilylocally convex. We include a few counterexamples to demonstrate that some ofour results do not carry over to general -algebras. The bilinearity and joint continuity of quasimultipliers on an -algebra are obtained under the assumption of strong factorability. Further, we establish several properties of the strict andquasistrict topologies on the algebra () of quasimultipliers of a complete-normed algebra having a minimal ultra-approximate identity
