Solução do tipo peakon para uma equação evolutiva de terceira ordem

Abstract: Resumo Neste trabalho, mostramos que uma equação evolutiva de terceira ordem que admite a solução Soliton, admite também a solução do tipo Peakon.Palavras-chave. Equação evolutiva, simetrias de Lie, Soliton, Peakon. IntroduçãoImagine que você está sentado em um parque, e que nesse parque passe um rio raso, de forma que seu comprimento seja muito maior que sua largura. Suponha que você esteja distante o suficiente para enxergar um pato nadando sobre o rio. Em um dado momento o pato para de nadar e fica boiando,… Show more

“…An important question raised in [42] is if, for some , equation (1) could be transformed into the KdV equation. We answered this question positively: actually, the response is just equation (38). Moreover, we also exhibited a Lax pair for it.…”
