2D quantum gravity at three loops: A counterterm investigation
We analyze the divergences of the three-loop partition function at fixed area in 2D quantum gravity. Considering the Liouville action in the Kähler formalism, we extract the coefficient of the leading divergence ∼AΛ2(lnAΛ2)2. This coefficient is non-vanishing. We discuss the counterterms one can an...
