Local symmetry and the dependence on extended spacetime
Keith Glennon, Peter West
We show that linearised E theory possesses a local symmetry at low levels provided the parameters of the local symmetry obey differential conditions that restrict their dependence…
Extended BMS representations and strings
Romain Ruzziconi, Peter West
We construct in detail the irreducible representations of the BMS group with super rotations in three and four dimensions that have the same rest frame momenta as the massive and m…
Duality symmetries and phase space quantum theory
Thomas Curtright, Peter West
We argue that duality symmetries can be manifestly realised when theories with these symmetries are quantised using phase space quantum theory. In particular, using background fiel…
Base Models Beat Aligned Models at Randomness and Creativity
Peter West, Christopher Potts
Alignment has quickly become a default ingredient in LLM development, with techniques such as reinforcement learning from human feedback making models act safely, follow instructio…
The discovery of supergravity and its early development
Peter West
I give an account of the discovery of supergravity and the first six years of its development which lead to the most general coupling of supergravity to matter. I restrict the disc…
Local symmetry and extended spacetime
Peter West
We show that the previously proposed local transformations in E theory have a closing algebra if one adopts a simple constraint on the parameters of the transformations that constr…
