AdS gravity and field theories at fixpoints
Klaus Behrndt
The renormalization group flow of the worldvolume theory depends very much from the number of unbroken supersymmetries. In the dual picture we break supersymmetry by adding d…
Branes in N=2,D=4 sugra and the conformal field theory limit
Klaus Behrndt
In this article we summarise the brane solutions (instantons, black holes and strings) in 4 dimensions when embedded in N=2 supergravity. Like in 10 dimensions these solutions are…
Entropy of bound states in the matrix description of M5-branes
Klaus Behrndt, Ilka Brunner
Like the M-theory itself also the worldvolume theory of the M5-brane contains brane excitations, which can be extracted from the supersymmetry algebra. Bound states (intersecting b…
Decompactification near the horizon and non-vanishing entropy
Klaus Behrndt
Intersecting D-brane configurations are related to black holes in D=4. Using the standard way of compactification only the Reissner-Nordstrøm black hole is non-singular. In this pa…
String duality and massless string states
K. Behrndt
We are discussing the \& duality for special class of heterotic string configurations. This class of solutions includes various types of black hole solutions and Taub-NUT g…
Creation of a scalar potential in 2D dilaton gravity
K. Behrndt
We investigate quantum corrections of the 2-d dilaton gravity near the singularity. Our motivation comes from a s-wave reduced cosmological solution which is classically singular i…
