Microscopic- versus Effective Coupling in N=2 Yang-Mills With Four Flavours
Ivo Sachs, William Weir
We determine the instanton corrections to the effective coupling in SU(2), N=2 Yang-Mills theory with four flavours to all orders. Our analysis uses the S(2,Z)-invariant curve and…

Electric Black Holes in Type 0 String Theory
Ivo Sachs
We discuss AdS_{2+1} (BTZ) black holes arising in type 0 string theory corresponding to D1-D5 and F1-NS5 bound states. In particular we describe a new family of non-dilatonic solut…
