Positive Semigroups of Operators, and Applications 18 Manfred Giebenhain nimmt den LeserThis means that semigroup theory may be applied directly to the study of the equation I'!. f = h on M. In [45] Yau proves that, for h ~ 0, there are no nonconstant, nonnegative solutions f in [j' for 1 < p < 00. From this, Yau gets the geometric fact that complete noncom pact Riemannian manifolds with nonnegative Ricci curvature must have infinite volume, a result which was announced earlier by Calabi [4]. 6. Concluding Remarks In several of the above
