摘要: 用有向图描述有限子移位,给出了有限子移位为拓扑混合的充要条件。在此基础上,利用非负方阵的 置换标准形证明了谱分解定理。重新考察了二次映射双曲不变集的存在性,并对现有论证作了若干补充。Abstract: Aneeessaandsuffieienteondition15givenfortopologieallymedfinitesubshiftsthatare deseribedbydireetedgraPhs.Basedonthisresult,thesPeetraldeeompositiontheoremsareProvedby usingpermutationeanoniealformsofnonnegativematriees.Theexisteneeofhypetholieinvariantset possessedbythequadratiemap15re一examined.Somedetailsmissedintherefereneesareprovidedand anewtyPeoffinitesubshiftsisfound.
