Abstract : In this talk, three-level BDDC algorithms will be presented for the solutions of large sparselinear algebraic systems arising from the mortar discretization of elliptic boundary value problems.The mortar discretization is considered on geometrically non-conforming subdomain partitions.In the algorithms, the large coarse problems from two-level BDDC algorithms are solvedapproximately while a good rate of convergence is maintained. This is an extension of previouswork for the three-level BDDC algorithms with standard finite element discretization byTu [12,13]. Estimates of the condition numbers are provided for the three-level BDDC methodsand numerical experiments are also discussed.
