BRST cohomology of timelike Liouville theory
Teresa Bautista, Harold Erbin, Matěj Kudrna
We compute the Hermitian sector of the relative BRST cohomology of the spacelike and timelike Liouville theories with generic real central charge in each case, coupled to a s…

Lorentzian CFT 3-point functions in momentum space
Teresa Bautista, Hadi Godazgar
In a conformal field theory, two and three-point functions of scalar operators and conserved currents are completely determined, up to constants, by conformal invariance. The expre…

Quantum Gravity from Timelike Liouville theory
Teresa Bautista, Atish Dabholkar, Harold Erbin
A proper definition of the path integral of quantum gravity has been a long-standing puzzle because the Weyl factor of the Euclidean metric has a wrong-sign kinetic term. We propos…
