abstract = {<p style="text-align: justify;">The optimal preconditioner and the superoptimal preconditioner were
proposed in 1988 and 1992 respectively. They have been studied
widely since then. Recently, Chen and Jin [6] extend
the superoptimal preconditioner to a more general case by using the
Moore-Penrose inverse. In this paper, we further study some useful
properties of the optimal and the generalized superoptimal
preconditioners. Several existing results are extended and new
properties are developed.</p>},
