Additionally we relate the theory of Fredholm determinants of integrable kernels and the theory of isomonodromic tau function. Using the Riemann-Hilbert problem mentioned above we construct a suitable Lax pair formalism for the Pearcey gap probability and re-derive the two nonlinear PDEs recently found and additionally find a third one not reducible to those.", "revisions": [ { "version": "v6", "updated": "2011-03-31T03:04:05.000Z" } ], "analyses": { "keywords": [ "riemann-hilbert approach", "transition", "deift-zhou steepest descent analysis", "suitable lax pair formalism", "isomonodromic tau function" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 43, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010arXiv1005.4083B" } } }
