On the final-state problem for the 1D cubic NLS
Gong Chen, Yongyu Qiang
We consider the one-dimensional cubic nonlinear Schrödinger equation $$ \ii\partial_tu+\frac12\partial_{xx}u=\la|u|^2u,\,λ=\pm 1 $$ and solve the final-state (modified wave opera…

Classification of Rational Functions of Degree Three over Finite Fields
Xiang-dong Hou, Siyu Peng, Yongyu Qiang +1
We study rational functions over finite fields under PGL-equivalence. We say that are \emph{equivalent} if there exist of degree one…
