Deparametrization of General Relativity by Space-Time Filling Unstable D9-Brane with Arbitrary Value of Tachyon
arXiv:2406.19487
Abstract
We calculate algebra of constraints of deparametrized General Relativity with space-time filling unstable D-brane for arbitrary value of tachyon field T. We also propose observables that have vanishing Poisson brackets with all first class constraints.
