Grossberg–Karshon twisted cubes and hesitant walk avoidance
We consider the initial value problem for cubic derivative nonlinear Schrödinger equations possessing weakly dissipative structure in one space dimension.We show that the small data solution decays like O((log t) -1/4 ) in L 2 as t → +∞.Furthermore, we find that this L 2 -decay rate is optimal by …
