Survey on Progress for Asymptotic Speed of Propagation and Traveling Wave Solutions of Some Types of Evolution Equations

The asymptotic speed of propagation and the existence of traveling solutions are two very important topics in the study of nonlinear evolution equations.Because of their strong backgrounds in applicable sciences such as physics and epidemics etc,and the interesting and challenging mathematical problems appearing in the study,they have been paid more and more attentions by the mathematicians and physicists.During the past thirty years,especially in the recent ten years,there are a great deal of excellent res...
