I will start by reviewing some classical works (of Fisher, Kolmogorov-Petrovsky-Piscunov, and Skellam) on traveling waves and constant spreading speed. I will then look at the theory of Aronson-Weinberger that describes the spreading by suitable Cauchy problems. Finally I will describe some recent theory obtained with my collaborators based on free boundary value problems, and compare it with results arising from the Cauchy problem along the lines of Aronson-Weinberger.
