TITLE Three Useful Preconditioners in Structured Matrix Computations

ABSTRACT In recent years, many preconditioners are proposed in structured matrix computations. In this talk, we will discuss three of them which are proved to be efficient in practice. We describe several mathematical properties of the preconditioners. Some spectral relations between preconditioned matrices are given. The preconditioners are also studied from the operator viewpoint.
