Query: Global Solutions of Semilinear Parabolic Equations on Negatively Curved
  Riemannian Manifolds   We are concerned with global existence for semilinear parabolic equations on
Riemannian manifolds with negative sectional curvatures. A particular attention
is paid to the class of initial conditions which ensure existence of global
solutions. Indeed, we show that such a class is crucially related to the
curvature bounds.
