AdS supergravity, holography and Ward identities
L. Andrianopoli, B. L. Cerchiai, R. Matrecano +5
We develop in detail the holographic framework for an pure AdS supergravity model in four dimensions, including all the contributions from the fermionic fields and…

Spin frame transformations and Dirac equations
R. Noris, L. Fatibene
We define spin frames, with the aim of extending spin structures from the category of (pseudo-)Riemannian manifolds to the category of spin manifolds with a fixed signature on them…

Taming boundary condition changing operator anomalies with the tachyon vacuum
Theodore Erler, Carlo Maccaferri, Ruggero Noris
Motivated by the appearance of associativity anomalies in the context of superstring field theory, we give a generalized solution built from boundary condition changing operators w…
