Open and Closed String Vertices for branes with magnetic field and T-duality
I. Pesando
We discuss carefully the vertices which describe the dipole open strings and closed strings on a D-brane with magnetic flux on a torus. Translation invariance along closed cycles f…

Exotic instanton counting and heterotic/type I' duality
Marco Billo', Livia Ferro, Marialuisa Frau +3
We compute the partition function for the exotic instanton system corresponding to D-instantons on D7 branes in Type I' theory. We exploit the BRST structure of the moduli action a…
