Wave breaking in the Ostrovsky-Hunter equation
SIAM Journal of Mathematical Analysis 42, 1967–1985 (2010)
The Ostrovsky–Hunter equation governs evolution of shallow water waves on a rotating
fluid in the limit of small high-frequency dispersion. Sufficient conditions for the
wave breaking in the Ostrovsky–Hunter equation are found both on an infinite line and
in a periodic domain. Using the method of characteristics, we also specify the blow-up
rate at which the waves break. Numerical illustrations of the finite-time wave breaking
are given in a periodic domain.
