摘要：

We consider the Cauchy problem associated with the Chern-Simons-Dirac system in R1+2. Using gauge invariance, we reduce the Chern-Simons-Dirac system to a Dirac equation and we uncover the null structure of this Dirac equation. Next, relying on null structure estimates, we establish that the Cauchy problem associated with this Dirac equation is locally-in-time well-posed in the Sobolev space H-s for all s > 1/4. Our proof uses modified L-4-type estimates.
