Bisingular $(\ddot{I},\hat{I}´)$ pseudodifferential operators on products of compact Lie groups

G. Drei, S. Federico, A. Parmeggiani

In this paper we develop the $(\ddot{I},\hat{I}´)$ calculus of bisingular pseudodifferential operators on the product compact Lie groups, which extends the one that was earlier introduced by t…
