Gravitational Instantons from Gauge Theory
Hyun Seok Yang, Mario Salizzoni
A gauge theory can be formulated on a noncommutative (NC) spacetime. This NC gauge theory has an equivalent dual description through the so-called Seiberg-Witten (SW) map in terms…
ALE spaces from noncommutative U(1) instantons via exact Seiberg-Witten map
Mario Salizzoni, Alessandro Torrielli, Hyun Seok Yang
The exact Seiberg-Witten (SW) map of a noncommutative (NC) gauge theory gives the commutative equivalent as an ordinary gauge theory coupled to a field dependent effective metric.…
D-branes in overcritical electric fields
Harald Dorn, Mario Salizzoni, Alessandro Torrielli
We collect some arguments for treating a D-brane with overcritical electric field as a well-posed initial condition for a D-brane decay. Within the field theoretical toy model of M…
Comments on the scalar propagator in AdS x S and the BMN plane wave
H. Dorn, M. Salizzoni, C. Sieg
We discuss the scalar propagator on generic AdS_{d+1} x S^{d'+1} backgrounds. For the conformally flat situations and masses corresponding to Weyl invariant actions the propagator…
On the propagator of a scalar field in AdS x S and in its plane wave limit
Harald Dorn, Mario Salizzoni, Christoph Sieg
We discuss the scalar propagator on generic AdS x S backgrounds. For the conformally flat situations and masses corresponding to Weyl invariant actions, the propagator is powerlike…
Topics in String Field Theory
L. Bonora, C. Maccaferri, D. Mamone +1
This review of bosonic string field theory is concentrated on two main subjects. In the first part we revisit the construction of the three string vertex and rederive the relevant…
