Flat-brane Compactifications in Supergravity Induced by Scalars
Alex Kehagias, Constantina Mattheopoulou
We discuss flat compactifications of supergravities in diverse dimensions in the presence of branes. The compactification is induced by the scalar fields of supergravity and it is…
Three-dimensional AdS gravity and extremal CFTs at c=8m
Spyros D. Avramis, Alex Kehagias, Constantina Mattheopoulou
We note that Witten's proposed duality between extremal c=24k CFTs and three-dimensional anti-de Sitter gravity may possibly be extended to central charges that are multiples of 8,…
Scalar-Induced Compactifications in Higher Dimensional Supergravities
Alex Kehagias, Constantina Mattheopoulou
We discuss compactifications of higher dimensional supergravities which are induced by scalars. In particular, we consider vector multiplets coupled to the supergravity multiplet i…
