%0 Journal Article %T Differential Harnack Estimates for Fisher's Equation %A Xiaodong Cao %A Bowei Liu %A Ian Pendleton %A Abigail Ward %J Mathematics %D 2015 %I arXiv %X In this paper, we derive several differential Harnack estimates (also known as Li-Yau-Hamilton-type estimates) for positive solutions of Fisher's equation. We use the estimates to obtain lower bounds on the speed of traveling wave solutions and to construct classical Harnack inequalities. %U http://arxiv.org/abs/1510.07606v1
