Global hypoellipticity of G-invariant operators on homogeneous vector bundles
摘要
We establish necessary and sufficient conditions for the global hypoellipticity of G-invariant operators on homogeneous vector bundles. These criteria are established in terms of the corresponding matrix-valued symbols as developed by Ruzhansky and Turunen and extended in (Pseudo-differential operators on Homogeneous vector bundles over compact homogeneous manifolds, arXiv:2403.08990) to homogeneous vector bundles.
