内容摘要:

We deal with entire solutions of bistable reaction-convection-diffusion equation in multiple half-lines with a junction. By characterizing the asymptotic behavior of the front waves as t→−∞ and constructing appropriate sub-solutions and super-solutions, we establish new type of entire solutions, and prove that these entire solutions converge to the front waves in some of half-lines and converge to zero in the remaining half-lines as t→−∞. We also consider the stability of the entire solutions.
