One of our main contributions is the uncovering of a null structure of (CSD). Combined with the standard machinery of $X^{s,b}$ spaces, we obtain local well-posedness of (CSD) for initial data $a_{\\mu}, \\psi \\in H^{1/4+\\epsilon}_{x}$. Moreover, it is observed that the same techniques applied to (CSH) lead to a quick proof of local well-posedness for initial data $a_{\\mu} \\in H^{1/4+\\epsilon}_{x}$, $(\\phi, \\partial_{t} \\phi) \\in H^{3/4+\\epsilon}_{x} \\times H^{-1/4+\\epsilon}_{x}$, which improves the previous result of Selberg-Tesfahun (2012).", "revisions": [ { "version": "v1", "updated": "2012-09-18T03:56:29.000Z" } ], "analyses": { "keywords": [ "low regularity solutions", "lorenz gauge", "chern-simons-higgs equations", "local well-posedness", "chern-simons-dirac" ], "note": { "typesetting": "TeX", "pages": 18, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1186657, "adsabs": "2012arXiv1209.3841H" } } }
