Consider the nonlinear Boltzmann solution near Maxwellians under in-flow, diffuse, or bounce-back boundary conditions. We demonstrate that discontinuity is created at the non-convex part of the grazing boundary, then propagates only along the forward characteristics inside the domain before it hits on the boundary again.", "revisions": [ { "version": "v1", "updated": "2010-07-12T21:36:53.000Z" } ], "analyses": { "keywords": [ "boltzmann equation", "non-convex domains", "propagation", "discontinuity", "nonlinear boltzmann solution" ], "tags": [ "journal article" ], "publication": { "publisher": "Springer", "journal": "Communications in Mathematical Physics", "year": 2011, "month": "Dec", "volume": 308, "number": 3, "pages": 641 }, "note": { "typesetting": "TeX", "pages": 39, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011CMaPh.308..641K" } } }
