In this talk, nonexistence of positive solutions of a fast diffusion type equation will be presented on a bounded domain $\Omega$ in a complete non compact Riemannian manifold $M$. Also new Hardy and Leray type inequalities with remainder terms on $M$ will be proved. Finally, on a model manifold hyperbolic space $\mathbb{H}^n$, several nonexistence results will be presented with the help of Hardy and Leray type inequalities.
