On the generalized AOR and CG iteration methods for a class of block two-by-two linear systems

In this work, we utilize the generalized AOR (GAOR) and CG (GCG) methods for constructing iteration methods to solve the block two-by-two linear systems which arise from the solution of the complex symmetric linear systems of equations. In order to compare the GAOR and GCG methods with some existing methods, we present some numerical examples to illustrate the performance of these methods.
