I am interested in using AMG for PETSc, where my matrices are complex. I looked at the documentation for Hypre and I'm not sure that it supports complex arithmetic. I also looked at ML from trilinos, however the only work around would be to recast my problem as a real system (doubling the MATVEcs). Any suggestions?</blockquote>
