## Traveling curved fronts in monotone bistable systems

 1 School of Mathematics and Statistics, Lanzhou University, Lanzhou, Gansu 730000

Received  January 2011 Revised  October 2011 Published  February 2012

This paper is concerned with the existence, uniqueness and stability of traveling curved fronts for reaction-diffusion bistable systems in two-dimensional space. By establishing the comparison theorem and constructing appropriate supersolutions and subsolutions, we prove the existence of traveling curved fronts. Furthermore, we show that the curved front is globally stable. Finally, we apply the results to three important models in biology.
