Abstract: We obtain the growth of Sobolev norms of the solution to the Maxwell–Dirac equations in R1+1 by applying elementary techniques. In particular, we estimate L∞ bound of the solution by making use of a local energy conservation. The similar idea can be applied to the Dirac–Klein–Gordon equations.

Keywords: Maxwell–Dirac, Dirac–Klein–Gordon, L^∞ bound, growth of Sobolev norms
