Time: 16:00-17:00, May 15th (Friday). Room: LBB-301. Speaker: Prof. YuanWei QI (University of Central Florida, USA). Title: Global Dynamics and Traveling Fronts of auto-catalytic chemical reaction. Abstract. In this talk, I shall report some recent results on auto-catalytic chemical reaction of Quadratic and Cubic order. Using the combination of a priori estimate and Renormalization Group method, it is shown that sharp result on global dynamics with critical nonlinearity can be obtained. In addition, a much better bounds on minimum speed for travling waves is established using novel approach and generating of waves from an initial setup is rigorously proved.
