Effective action and Hawking radiation for dilaton coupled scalars in two dimensions
W. Kummer, D. V. Vassilevich
The effective one-loop action for general dilaton theories with arbitrary dilaton-dependent measure and nonminimal coupling to scalar matter is computed. As an application we deter…
Universal conservation law and modified Noether symmetry in 2d models of gravity with matter
W. Kummer, G. Tieber
It is well-known that all 2d models of gravity---including theories with nonvanishing torsion and dilaton theories---can be solved exactly, if matter interactions are absent. An ab…
D=10 super-D9-brane
V. Akulov, I. Bandos, W. Kummer +1
Superfield equations of motion for D=10 type IIB Dirichlet super-9-brane are obtained from the generalized action principle. The geometric equations containing fermionic superembed…
Comment on: ``Trace anomaly of dilaton coupled scalars in two dimensions''
W. Kummer, H. Liebl, D. V. Vassilevich
The trace anomaly for nonminimally coupled scalars in spherically reduced gravity obtained by Bousso and Hawking (hep-th/9705236) is incorrect. We explain the reasons for the devia…
