Low regularity and local well-posedness for the 1+3 dimensional Dirac-Klein-Gordon system. <i>Electronic Journal of Differential Equations, 2007</i>(162), pp. 1-26.1072-6691https://hdl.handle.net/10877/14376We prove that the Cauchy problem for the Dirac-Klein-Gordon system of equations in 1+3 dimensions is locally well-posed in a range of Sobolev spaces for the Dirac spinor and the meson field. The result contains and extends the earlier known results for the same problem. Our proof relies on the null structure in the system, and bilinear spacetime estimates of Klainerman-Machedon type.Text26 pages1 file (.pdf)enAttribution 4.0 InternationalDirac equationKlein-Gordon equationLow regular solutionsLocal well-posednessArticle
