Scattering for the focusing, $ L^2 $-supercritical fourth-order NLS in one dimension.

In this paper, we consider the fourth-order Schrödinger equations with focusing, $ L^2 $-supercritical nonlinearity in one dimension. We prove the global existence and scattering of even solutions below the ground state threshold, under the assumption that the threshold for even solutions is less than a certain constant times the threshold for general solutions.
