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…
Topological B-model and String Theory
Seungjoon Hyun, Kyungho Oh, Jong-Dae Park +1
We study the topological B-model on a deformed orbifolded conifold by investigating variation of complex structures via quantum Kodaira-Spencer theories. The fermionic/brane…
Open-Closed String Duality from Orbifolded Conifolds
Seungjoon Hyun, Kyungho Oh
We study large N dualities for a class of theories realized on type IIB D5 branes wrapping 2-cycles of local Calabi-Yau threefolds which is obtained from resolving o…
Orbifolds, Penrose Limits and Supersymmetry Enhancement
Kyungho Oh, Radu Tatar
We consider supersymmetric PP-wave limits for different N=1 orbifold geometries of the five sphere S^5 and the five dimensional Einstein manifold T^{1,1}. As there are several inte…
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…
Geometric Transition versus Cascading Solution
Keshav Dasgupta, Kyungho Oh, Jaemo Park +1
We study Vafa's geometric transition and Klebanov - Strassler solution from various points of view in M-theory. In terms of brane configurations, we show the detailed equivalences…
