Higher Order Asymptotics of Decaying Solutions of some Generalized Burgers Equations
Gastão A. Braga, Frederico Furtado, Jussara M. Moreira +1
We study the large-time behavior of solutions to a generalized Burgers Equation, with initial zero mass data. Our main purpose is to present a modified version of the Renormalizati…
