abstract = {<p style="text-align: justify;">Many physical processes are described by elliptic or parabolic partial differential
equations. For linear stability problems associated with such equations, the
inverse Laplacian provides a very effective preconditioner. In addition, it is also readily
available in most scientific calculations in the form of a Poisson solver or an implicit
diffusive time step. We incorporate Laplacian preconditioning into the inverse Arnoldi
method, using BiCGSTAB to solve the large linear systems. Two successful implementations
are described: spherical Couette flow described by the Navier-Stokes equations
and Bose-Einstein condensation described by the nonlinear Schrödinger equation.</p>},
