A spinor-adapted geometric approach for nonlinear Dirac systems and its application to a tensorial wave-Dirac system near Minkowski spacetime

Seokchang Hong

We study a nonlinear tensorial wave-Dirac system on -dimensional asymptotically flat spacetimes as a semilinear model motivated by the Maxwell-Dirac and Einstein-Dirac syste…

A Note on the smoothness of flow maps for the Yang-Mills system in the Lorenz gauge

Seokchang Hong

We study the failure of the smoothness of flow maps for the dimensional Yang-Mills system in the Lorenz gauge by Knapp type counterexamples. This shows a gap between the sc…
