Higher Order Asymptotics of Decaying Solutions of some Generalized Burgers Equations
@inproceedings{Braga2022HigherOA, title={Higher Order Asymptotics of Decaying Solutions of some Generalized Burgers Equations}, author={Gast{\~a}o A. Braga and Frederico Furtado and Jussara M. Moreira and Antonio Marcos da Silva}, year={2022} }
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 Renormalization Group map, which is able to provide the higher order asymptotic properties of the solution to the Cauchy problem of a class of nonlinear time-evolution problems.

The study of waves can be traced back to antiquity where philosophers, such as Pythagoras, studied the relation of pitch and length of string in musical instruments and the subject of classical acoustics was laid down and presented as a coherent whole by John William Strutt in his treatise Theory of Sound.
