On fredholm riggings of G-translators

We consider riggings of G-translators on manifolds with multidimensional singularities. We derive a condition for the ellipticity of G-riggings, prove the finiteness theorem, and analyze the relationship between the notions of G-ellipticity and ordinary ellipticity of the riggings. The interest in this class of operators arises in connection with the study of nonlocal pseudodifferential operators. © 2012 Pleiades Publishing, Ltd.
