Survey on global existence in the nonliner Dirac equations in one dimension

"Harmonic Analysis and Nonlinear Partial Differential Equations" (Editors T. Ozawa and M. Sugimoto), RIMS Kokyuroku Bessatsu, B26, 37-50 (2011)

We consider the nonlinear Dirac equations in one dimension and review various results on global existence of solutions in H1. Depending on the character of the nonlinear terms, existence of the large-norm solutions can be extended for all times. Global existence of the small-norm solutions is proved for the most general nonlinear Dirac equations with cubic and higher-order nonlinear terms. Integrability of the massive Thirring model is used to find conditions that no solitons occur in the Cauchy problem with small initial data in a subspace of L2.
