Abstract: Following the work of Duistermaat and Singer on isomorphisms of algebras of global pseudodifferential operators, we classify order preserving isomorphisms of algebras of microlocally defined semiclassical pseudodifferential operators. Specifically, we show that any such isomorphism is given by conjugation by , where
is a microlocally elliptic semiclassical pseudodifferential operator and
is a microlocally unitary
-FIO associated to the graph of a local symplectic transformation.
