Abstract: In this talk, I talk about the existence of martingale solutions to the stochastic heat equation in a Riemannian manifold by using suitable Dirichlet form on the Riemannian path and loop space. Finally, by using Anderson-Driver's Approximation, we give a form of the equation associated with the process given by Dirichlet form. Moreover, we establish the Log-Sobolev inequality for the stochastic heatequation. In addition, some characterizations for the lower or pinned bounds ofthe Ricci curvature are presented related to the stochastic heat equation.
