Elliptic- and hyperbolic-function solutions of the nonlocal reverse-time
and reverse-space-time nonlinear Schrödinger equations
Abstract
In this paper, we obtain the stationary elliptic- and
hyperbolic-function solutions of the nonlocal reverse-time and
reverse-space-time nonlinear Schrödinger (NLS) equations based on their
connection with the standard Weierstrass elliptic equation. The
reverse-time NLS equation possesses the bounded dn-, cn-, sn-, sech-,
and tanh-function solutions. Of special interest, the tanh-function
solution can display both the dark- and antidark-soliton profiles. The
reverse-space-time NLS equation admits the general Jacobian
elliptic-function solutions (which are exponentially growing at one
infinity or display the periodical oscillation in x), the bounded dn-
and cn-function solutions, as well as the K-shifted dn- and sn-function
solutions. At the degeneration, the hyperbolic-function solutions may
exhibit an exponential growth behavior at one infinity, or show the
gray- and bright-soliton profiles.
