Integral representations of -divergences for general von Neumann algebras
Ricardo Correa da Silva, Markus B. Fröb, Gandalf Lechner +1
We define and analyze hockeystick divergences and -divergences for normal positive functionals on general von Neumann algebras, generalizing and unifying previous work in classi…

Vekua-Type Operators on Compact Lie Groups: Hypoellipticity, Solvability, and Self-Duality
Alexandre Kirilov, Ricardo Paleari da Silva
We study global hypoellipticity and global solvability for Vekua-type operators associated with diagonal left-invariant operators on compact Lie groups. The conjugation term produc…

Diagonal systems of differential operators on compact Lie groups
Paulo L. Dattori da Silva, Alexandre Kirilov, Ricardo Paleari da Silva
We investigate the global hypoellipticity and global solvability of systems of left-invariant differential operators on compact Lie groups. Focusing on diagonal systems, we establi…
