abstract = {<p style="text-align: justify;">We consider a nonsymmetric Toeplitz system which arises in the discretization
of a partial integro-differential equation in option pricing problems. The preconditioned
conjugate gradient method with a tri-diagonal preconditioner is used to solve
this system. Theoretical analysis shows that under certain conditions the tri-diagonal
preconditioner leads to a superlinear convergence rate. Numerical results exemplify our
theoretical analysis.</p>},
