Fredholm conditions for operators invariant with respect to compact Lie group actions

Alexandre Baldare, Rémi Côme, Victor Nistor

Let $G$ be a compact Lie group acting smoothly on a smooth, compact manifold $M$, let $P\in {\psi }^m(M;E_0,E_1)$ be a $G$--invariant, classical pseudodifferential operator acting bet…
