Abstract

In this work we characterise the H\"ormander classes \symbClassOnmρδ\group,Ho¨r\symbClassOn{m}{\rho}{\delta}{\group,\textnormal{H\"or}} on the open manifold \group=(1,1)n\group = (-1,1)^n. We show that by endowing the open manifold \group=(1,1)n\group = (-1,1)^n with a group structure, the corresponding global Fourier analysis on the group allows one to define a global notion of symbol on the phase space \group×Rn\group \times \R^n. Then, the class of pseudo-differential operators associated to the global H\"ormander classes \symbClassOnmρδ\group×Rn\symbClassOn{m}{\rho}{\delta}{\group \times \R^n} recovers the H\"ormander classes \symbClassOnmρδ\group,loc\symbClassOn{m}{\rho}{\delta}{\group,\textnormal{loc}} defined by local coordinate systems. The analytic and qualitative properties of the classes \symbClassOnmρδ\group×Rn\symbClassOn{m}{\rho}{\delta}{\group \times \R^n} are presented in terms of the corresponding global symbols. In particular, LpL^p-Fefferman type estimates and Calder\'on-Vaillancourt theorems are analysed, as well as the spectral properties of the operators.
