On the principal eigenfunction of positive elliptic differential operators and the prescription of $Q$-curvature on closed Riemannian manifolds

Abstract

In this note we establish the large time non-negativity of the heat kernel for a class of elliptic differential operators on closed, Riemannian manifolds, and apply this result to a problem from conformal differential geometry.
