Rational curves on blowing-ups of projective spaces
Bumsig Kim, Yongnam Lee, Kyungho Oh
We prove the irredcibility (and the rational connectedness) of the moduli spaces of (free) morphisms from a projective line to a successive blowing-up of a product of projective sp…

Duality and Confinement in N=1 Supersymmetric Theories from Geometric Transitions
Kyungho Oh, Radu Tatar
We study large N dualities for a general class of N=1 theories realized on type IIB D5 branes wrapping 2-cycles of local Calabi-Yau threefolds or as effective field theories on D4…

Comments on Brane Configurations with Semi-infinite D4 Branes
Kyungho Oh, Radu Tatar
We consider four dimensional supersymmetric gauge field theories from brane configurations with the matter content given by semi-infinite D4 branes ending on both sides of NS brane…
