Abstract

Go to

The aim of this paper is to show the local well-posedness of 2 dimensional Dirac equations with power type and Hartree type nonlinearity derived from honeycomb structure in $H^s$ for $s>\frac78$ and $s>\frac38$, respectively. We also provide the smoothness failure of flows of Dirac equations.

Keywords: Dirac equations, honeycomb lattice, local well-posedness, non-smoothness, Bourgain's space
