    • Semilinear Li and Yau inequalities
    Authors: Daniele, Castorina; Giovanni, Catino; Carlo, Mantegazza;  Advisor: -;  Co-Author: - (2022)

    We derive an adaptation of Li and Yau estimates for positive solutions of semilinear heat equations on Riemannian manifolds with nonnegative Ricci tensor. We then apply these estimates to obtain a Harnack inequality and to discuss monotonicity, convexity, decay estimates and triviality of ancient and eternal solutions.
