Comments on Matrices & Spheres

Abstract: We study the partition function of quantum fields on the Euclidean sphere and its relation to the thermodynamics of the de Sitter horizon and the Gibbons-Hawking entropy. For the case of the two-sphere, we explore the relation between two-dimensional quantum gravity coupled to conformal matter and matrix integrals. We discuss how such two-dimensional models may shed light on Euclidean gravity with a positive cosmological constant.
