BMS algebra as an extension of the Poincaré symmetry in light-cone gravity
Sudarshan Ananth, Lars Brink, Sucheta Majumdar
We analyze possible local extensions of the Poincaré symmetry in light-cone gravity in four dimensions. We use a formalism where we represent the algebra on the two physical degree…
Asymptotic structure of the Rarita-Schwinger theory in four spacetime dimensions at spatial infinity
Oscar Fuentealba, Marc Henneaux, Sucheta Majumdar +2
We investigate the asymptotic structure of the free Rarita-Schwinger theory in four spacetime dimensions at spatial infinity in the Hamiltonian formalism. We impose boundary condit…
Asymptotic structure of the Pauli-Fierz theory in four spacetime dimensions
Oscar Fuentealba, Marc Henneaux, Sucheta Majumdar +2
The asymptotic structure of the Pauli-Fierz theory at spatial infinity is investigated in four spacetime dimensions. Boundary conditions on the massless spin- field that are inv…
Ehlers symmetry in four dimensions
Sucheta Majumdar
Starting with the light-cone Hamiltonian for gravity, we perform a field redefinition that reveals a hidden symmetry in four dimensions, namely the Ehlers symmetry. The f…
A hidden symmetry in quantum gravity
Sudarshan Ananth, Lars Brink, Sucheta Majumdar
The action integral contains more information than the equations of motion. We have previously shown that there are signs of an extended exceptional symmetry for N=8 supergravity i…
Maximal supergravity and the quest for finiteness
Sudarshan Ananth, Lars Brink, Sucheta Majumdar
We show that N = 8 supergravity may possess an even larger symmetry than previously believed. Such an enhanced symmetry is needed to explain why this theory of gravity exhibits ult…
