Adjoint L-Infinity Actions and Conserved Charges in GR
Changsun Choi, Ryan E. Grady
In this work we compute the conserved currents and charges associated to the action of an infinitesimal isometry (Killing field) in Einstein--Cartan--Palatini gravity. We offer a n…
DGLA Actions: An Application in GR
Ryan Grady
This note serves two purposes: 1) define actions by differential graded Lie algebras, and 2) apply such differential graded Lie symmetry in general relativity (GR) to constrain the…
Quantizing Derived Mapping Stacks
Ryan E. Grady
In this review we discuss several topological and geometric invariants obtained by quantizing -models. More precisely, we don't quantize the entire mapping stack of fields, but…
Homotopy RG Flow and the Non-Linear -model
Ryan Grady, Brian R. Williams
The purpose of this note is two give a mathematical treatment to the low energy effective theory of the two-dimensional sigma model. Perhaps surprisingly, our low energy effective…
