Two robust virtual element methods for the Brinkman equations

In this paper, we present two stable virtual element methods for the Brinkman equations robust in the Stokes and Darcy limits. We use a pair of stable virtual elements for the velocity and pressure. Firstly, we define an H ( div ) -conforming velocity reconstruction operator for the velocity test fu...
