The correspoding transmission eigenvalues satisfy the DMPK stochastic differential equations, like Dyson Brownian motion in the context of GOE/GUE random matrices. We control the singular repulsion terms of this SDE with a stopping-time argument, and its degenerate initial condition by an approximation procedure, and thereby establish the DMPK equation to be well posed.", "revisions": [ { "version": "v2", "updated": "2013-01-08T11:03:33.000Z" } ], "analyses": { "subjects": [ "60B20", "60H10", "60K35", "82D77" ], "keywords": [ "unique strong solution", "dmpk equation", "dmpk stochastic differential equations", "correspoding transmission eigenvalues satisfy", "dyson brownian motion" ], "note": { "typesetting": "TeX", "pages": 27, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2012arXiv1205.3396B" } } }
