摘要:
It is shown that the cubic derivative nonlinear Schrodinger equation is locally well-posed in Besov spaces B-2,infinity(s) (X), s >= 1/2, where we treat the non-periodic setting X = R and the periodic setting X = T simultaneously. The proof is based on the strategy of Herr for initial data in H-s (T), s >= 1/2.
