Maths HEP Lunchtime Seminars: Fractional D3-branes in diverse backgrounds
25 January 2002 13:00 in CM221
"In the first part of this talk, we will discuss fractional D3-branes supergravity solutions on orientifolded C^2/Z_2 orbifolds of type IIB string theory. The one-loop corrected gauge couplings for the symplectic or orthogonal groups living on the D-branes are reproduced on the world-volume of probes. In the second part, we will construct a D3-brane solution on the two-centers Taub-NUT manifold which interpolates between fractional D3-branes in the ALE space limit and a T-dual smeared type IIA configuration. Then, we will lift this configuration to M-theory and comment on the connection with wrapped M5-branes solutions."
