Auxiliary AMG preconditioner for Maxwell equations with jump coefficients

Yunrong Zhu


In this talk, I will explain auxiliary space preconditioning technique. Under this framework, we only need to construct certain stable decomposition of the finite element spaces to construct efficient preconditioners. Based on some regular decomposition results on H(curl), we construct a robust and efficient (AMG) preconditioner for Maxwell's equation with jump coefficients.
