Hiptmair–Xu preconditioner
text:
In mathematics, Hiptmair–Xu (HX) preconditioners are preconditioners for solving H and H problems based on the auxiliary space preconditioning framework. An important ingredient in the derivation of HX preconditioners in two and three dimensions is the so-called regular decomposition, which decomposes a Sobolev space function into a component of higher regularity and a scalar or vector potential. The key to the success of HX preconditioners is the discrete version of this decomposition, which is
