The $N$-elliptic localized solutions are expressed as (the derivative of) the ratios of determinants with entries in terms of Weierstrass-sigma functions. Moreover, the asymptotic behaviours of both two forms of $N$-elliptic localized solutions are analyzed both along and between the propagation directions as $t$ tends to infinity. This is a joint work with Wang Tang.
