-Bootstrap
Achilleas Gitsis, Falk Hassler, Luca Scala
Due to the exponential growth in the number of terms, computing -corrections to string theory's low-energy effective actions is a challenging matter. In order to fix all the co…

All-order generalized Green-Schwarz transformations
Achilleas Gitsis, Falk Hassler
Compatibility with T-duality severely constrains higher-derivative corrections to the low-energy supergravity limits of string theory. For example, it suggests that Lorentz transfo…

Unraveling the generalized Bergshoeff-de Roo identification
Achilleas Gitsis, Falk Hassler
We revisit duality-covariant higher-derivative corrections which arise from the generalized Bergshoeff-de Roo (gBdR) identification, a prescription that gives rise to a two paramet…
