Existence of -matrix approximants to the inverse of BEM matrices: the hyper-singular integral operator

Markus Faustmann, Jens Markus Melenk, Dirk Praetorius

We consider discretizations of the hyper-singular integral operator on closed surfaces and show that the inverses of the corresponding system matrices can be approximated by blockw…
