Abstract

In this paper we study the multigrid algorithm for a quad-curl problem based on [Formula presented] interior penalty method on bounded polygonal domains. It is shown that the contraction numbers of [Formula presented]-cycle multigrid algorithm for the [Formula presented] interior penalty method converge uniformly with rate of [Formula presented], where [Formula presented] is the number of pre-smoothing (and post-smoothing) steps, [Formula presented] is the index of elliptic regularity. The performance of the multigrid fast solver is illustrated by numerical results.
