Abstract
We give a stochastic proof of an extension of E Calabi’s strong maximum principle under some geometric conditions in the framework of strong Feller diffusion processes associated to local regular semiDirichlet forms with lower bounds As a corollary our notion of subharmonicity implies a notion of viscosity subsolution in a stochastic sense We can apply our result to singular geometric object like Alexandrov space limit space under spectral distance of Riemannian manifolds with uniform lower Ricci curvature bound and so on
