Ralf Kornhuber Monotone

We derive fast solvers for discrete elliptic variational inequalities of the second kind as resulting from the approximation by piecewise linear nite elements. Following the rst part of this paper, monotone multigrid methods are considered as extended underrelaxations. Again, the coarse grid corrections are localized by suitable constraints, which in this case are xed by ne grid smoothing. We c...

Galaxies in the infrared Ralf

The mid infrared spectra of the starbursts show the 9.7μm silicate absorption feature and strong mid infrared emission bands centered at 6.2, 7.7, and 11.3 μm. Illustrative models of the active galaxies are presented: As the starbursts are most likely confined to the central region of the galaxy the radiative transfer in the nucleus is solved under the assumption of spherical symmetry. The dist...
