An Overlapping Domain Decomposition Method with a Vertex-based Coarse Space for Raviart--Thomas Vector Fields

In this paper, we propose a two-level overlapping domain decomposition preconditioner for three dimensional vector field problems posed in $\HDiv$. We introduce a new coarse component, which reduces the computational complexity, associated with the coarse vertices. Numerical experiments are also presented.
