contents We parameterize the elliptic function solutions to the derivative nonlinear Schrödinger (DNLS) equation with four independent parameters and generate two equivalent forms of N-elliptic localized solutions to the DNLS equation through the Darboux-Bäcklund transformation. 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 behaviors of both forms of N-elliptic localized solutions are analyzed along and between the propagation directions as $t \rightarrow \pm\infty$, which verify that the collisions between elliptic-solutions are elastic. We prove that the solution tends to a simple elliptic localized solution along each propagation direction. Between the propagation directions, the solution asymptotically approaches a shifted background. Furthermore, we establish sufficient conditions for strictly elastic collisions. The dynamic behaviors of the solutions are systematically investigated, with analytical results visualized through graphical illustrations. The asymptotic analysis of these solutions confirms that they exhibit the behavior predicted by the generalized soliton resolution conjecture on the elliptic function background.
