On Bäcklund transformation for a generalized Burgers equation and solitonic solutions. (English) Zbl 0944.37045
Summary: By the application of the truncated Painlevé expansion and symbolic computation method, the authors show that Bäcklund transformations exist for a generalized Burgers equation of the form $$u_t+b(t)uu_x+a(t)u_{xx}=0$$ with some constraints. Kink-type solitonic solutions are found.
