Pseudodifferential operators on manifolds with linearization

We present in this paper the construction of a pseudodifferential calculus on smooth non-compact manifolds associated to a globally defined and coordinate independant complete symbol calculus, that generalizes the standard pseudodifferential calculus on Rn. We consider the case of manifolds M with linearization in the sense of Bokobza-Haggiag [4], such that the associated (abstract) exponential map provides global diffeomorphisms of M with Rn at any point. Cartan–Hadamard manifolds are special cases of such manifolds. The abstract exponential map encodes a notion of infinity on the manifold that allows, modulo some hypothesis of Sσ-bounded geometry, to define the Schwartz space of rapidly decaying functions, globally defined Fourier transformation and classes of symbols with uniform and decaying control over the x variable. Given a linearization on the manifold with some properties of control at infinity, we construct symbol maps and λ-quantization, explicit Moyal star-product on the cotangent bundle, and classes of pseudodifferential operators. We show that these classes are stable under composition, and that the λ-quantization map gives an algebra isomorphism (which depends on the linearization) between symbols and pseudodifferential operators. We study, in our setting, L-continuity and give some examples. We show in particular that the hyperbolic 2-space H has a S1-bounded geometry, allowing the construction of a global symbol calculus of pseudodifferential operators on S(H).
