Instantons and Toric Quiver Gauge Theories
Riccardo Argurio, Gabriele Ferretti, Christoffer Petersson
We show how to construct the general action coupling (multi)instantons to gauge theories arising from branes probing arbitrary toric singularities. We give a general set of rules f…
Fractional Branes and N=1 Gauge Theories
M. Bertolini, P. Di Vecchia, G. Ferretti +1
We discuss fractional D3-branes on the orbifold C^3/Z_2*Z_2. We study the open and the closed string spectrum on this orbifold. The corresponding N=1 theory on the brane has, gener…
D-brane probes on G2 Orbifolds
G. Ferretti, P. Salomonson, D. Tsimpis
We consider type IIB string theory on a seven dimensional orbifold with holonomy in G2. The motivation is to use D1-branes as probes of the geometry. The low energy theory on the D…
Regularization and Quantization of Higher Dimensional Current Algebras
G. Ferretti
We present some recently discovered infinite dimensional Lie algebras that can be understood as extensions of the algebra Map(M,g) of maps from a compact p-dimensional manifold to…
