In strong contrast, for any dynamical system $f:X\\rightarrow X$ with exponential specification property and a H$\\ddot{\\text{o}}$lder continuous matrix cocycle $A:X\\rightarrow G (m,\\mathbb{R})$, we show here that if there exist ergodic measures with different Lyapunov spectrum, then the Lyapunov-irregular set of $A$ is residual (i.e., containing a dense $G_\\delta$ set).", "revisions": [ { "version": "v1", "updated": "2015-05-18T00:02:09.000Z" } ], "analyses": { "keywords": [ "lyapunov exponents", "nonexistence", "lyapunov-irregular set", "oseledec multiplicative ergodic theorem", "invariant probability measure" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2015arXiv150504477T" } } }
