> *Abstract:*
>
> Maximum principles at infinity (or ”almost maximum principles”) are a
> powerful tool to investigate the geometry of Riemannian manifolds. Among
> them, we stress the Ekeland, the Omori-Yau principles and their weak
> versions, in the sense of Pigola-Rigoli-Setti. These last have nice
> probabilistic counterparts in terms of stochastic and martingale
> completeness, which in turn are related to potential theory and
> parabolicity. The validity of such principles is usually granted via
> suitable exhaustion functions called Evans-Khas’minskii potentials. In this
> talk, I discuss an underlying, unifying duality that allows to uncover
> relations between the principles. Indeed, duality holds for a broad class
> of fully-nonlinear operators of geometric interest. Our methods use the
> approach to nonlinear PDEs pioneered by Krylov (’95) and Harvey-Lawson (’09
> - ), and involve the study of viscosity “almost solutions” of obstacle type
> problems. This is joint work with Leandro F. Pessoa.
