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…

completion of the Friedmann equations
Stephen Angus, Kyoungho Cho, Guilherme Franzmann +2
In string theory the closed-string massless NS-NS sector forms a multiplet of symmetry. This suggests a specific modification to General Relativity in which the e…

Einstein Double Field Equations
Stephen Angus, Kyoungho Cho, Jeong-Hyuck Park
Upon treating the whole closed string massless sector as stringy graviton fields, Double Field Theory may evolve into Stringy Gravity, i.e. the stringy augmentation of General Rela…
