New anomaly free supergravities in six dimensions
Katrin Becker, Alex Kehagias, Ergin Sezgin +2
An extended search for anomaly free matter coupled supergravity in six dimension is carried out by two different methods which we refer to as the graphical and rank metho…
On running couplings in gauge theories from type-IIB supergravity
A. Kehagias, K. Sfetsos
We construct an explicit solution of type-IIB supergravity describing the strong coupling regime of a non-supersymmetric gauge theory. The latter has a running coupling with an ult…
Octonionic Gravitational Instantons
I. Bakas, E. Floratos, A. Kehagias
We construct eight-dimensional gravitational instantons by solving appropriate self-duality equations for the spin-connection. The particular gravitational instanton we present has…
Eight-Dimensional Self-Dual Spaces
E. G. Floratos, A. Kehagias
We discuss higher-dimensional gravitational instantons by studying appropriate self-duality equations for the spin connection. In seven and in eight dimensions, the corresponding s…
