DESCRIPTION:A proper definition of the path integral of quantum gravity ha
s been a long standing puzzle because the conformal factor of the Euclidea
n metric has a wrong-sign kinetic term. We propose a definition of two-di
mensional quantum gravity with cosmological constant using conformal boot
strap for the timelike Liouville theory coupled to supercritical matter.
We prove a no-ghost theorem for the states in the BRST cohomology. We show
that the four point function constructed by gluing the timelike DOZZ th
ree point functions is well-defined and crossing symmetric with the choi
ce of the Ribault-Santachiara contour for the internal momenta but with ex
ternal momenta corresponding to physical states in the BRST cohomology.\n
