Normal trace for vector fields of bounded mean oscillation

Functional Analysis 2020-11-25 v1

Abstract

We introduce various spaces of vector fields of bounded mean oscillation (BMOBMO) defined in a domain so that normal trace on the boundary is bounded when its divergence is well controlled. The behavior of "normal" component and "tangential" component may be different for our BMOBMO vector fields. As a result zero extension of the normal component stays in BMOBMO although such property may not hold for tangential components.
