The well-posedness and blow up phenomenon for a Tsunamis model with time-fractional derivative

This is the authors' abstract. We don't add key points for this paper.

This paper is concerned with the well-posedness of a time-fractional shallow-water equations, which has received little attention. In the realm of fractional calculus, numerous types of fractional derivatives have been explored in the literature. Among these, one of the most notable and well-structured ones is the conformable fractional derivative. In this paper, we delve into the local well-posedness of the fractional tsunami shallow-water mathematical model in the critical Besov space B3/22,1. Under some symmetric and sign conditions, we show that the strong solution will blow up in finite time.
