We study the actions of the Lie algebra nsl(2, C) of SL(2, C)n and the associated Casimir operator on the space of pseudodifferential operators of n variables, C denoting the complex numbers. We describe the effect of the Casimir operator on a pseudodifferential operator in connection with the symbol map and construct an nsl(2, C)-invariant lifting of the symbol map.
