Small-Instanton Transitions in F-theory
Stephen Angus, Kang-Sin Choi
We study the phase transition between G-instantons and D3-branes. A G-instanton is a classical solution to the self-dual equation of the M/F-theory four-form field strength G in th…

Transitions of Orbifold Vacua
Kang-Sin Choi, Tatsuo Kobayashi
We study the global structure of vacua of heterotic strings compactified on orbifolds (N=2,3) in the presence of heterotic 5-branes. Gauge symmetry breaking associated wi…
