Dj. Kaup et al., EFFECT OF A CHIRP ON SOLITON PRODUCTION, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 50(2), 1994, pp. 1635-1637
We revisit the problem of influence of a chirp on production of solito
ns by an initial pulse, considering the rectangular pulse shape and a
piecewise-constant chirp, which form of the pulse is very easy to anal
yze. We show that there is a critical value of the chirp, beyond which
individual solitons are split. This critical value is nearly constant
.
