Abstract. We use a parallel direct solver based on the Schur complement method for solving large sparse linear systems arising from the finite element method. A domain decompositi...

— In this paper we recursively estimate the magnetic and electric potential of the Earth’s Arctic region. We construct estimates based on data gathered from over 85 magnetomete...
