Abstract
We prove the local multiplicity at most one theorem underlying the definition and theory of local -, - and -factors, defined by virtue of the generalized doubling method, over any local field of characteristic 0. We also present two applications: one to the existence of local factors for genuine representations of covering groups, the other to the global unfolding argument of the doubling integral.
