On black hole singularity resolution in via duality-invariant corrections
Tomas Codina, Olaf Hohm, Barton Zwiebach
Starting with the two-derivative limit of string theory, we explore the space of T-duality invariant corrections, a space that contains a point representing the fully $α…
2D Black Holes, Bianchi I Cosmologies, and
Tomas Codina, Olaf Hohm, Barton Zwiebach
We report two surprising results on corrections in string theory restricted to massless fields. First, for critical dimension Bianchi type I cosmologies with scale factors…
Initial value problem in string-inspired nonlocal field theory
Harold Erbin, Atakan Hilmi Fırat, Barton Zwiebach
We consider a nonlocal scalar field theory inspired by the tachyon action in open string field theory. The Lorentz-covariant action is characterized by a parameter that quant…
Hyperbolic String Vertices
Kevin Costello, Barton Zwiebach
The string vertices of closed string field theory are subsets of the moduli spaces of punctured Riemann surfaces that satisfy a geometric version of the Batalin-Vilkovisky master e…
Duality Invariant Cosmology to all Orders in
Olaf Hohm, Barton Zwiebach
While the classification of corrections of string inspired effective theories remains an unsolved problem, we show how to classify duality invariant corrections for purel…
Non-perturbative de Sitter vacua via corrections
Olaf Hohm, Barton Zwiebach
The higher-derivative corrections consistent with duality invariance can be completely classified for cosmological, purely time-dependent backgrounds. This result is…
