On Itzykson-Zuber Ansatz
arXiv:1904.09071 · doi:10.1007/JHEP09(2019)075
Abstract
We apply the renormalized coupling constants and Virasoro constraints to derive the Itzykson-Zuber Ansatz on the form of the free energy in topological 2D gravity. We also treat the topological 1D gravity and the Hermitian one-matrix models in the same fashion. Some uniform behaviors are discovered in this approach.
