报告摘要  The classical subshifts of finite type (SFTs) code uniformly hyperbolic diffeomorphisms. Interval maps have very similar property, though most of them cannot be coded by SFTs. I will introduce subshifts of quasi-finite type (QFTs). They generalize SFTs, code interval maps as well as some natural families of multi-dimensional maps. They naturally give rise to Strongly Positively Recurrent topological Markov shifts which share many of the good properties of SFTs, including a spectral gap and the exponential decay of correlations.
