摘要：For a contractive iterated function system (IFS), it is known that there is a natural hyperbolic graph structure (augmented tree) on the symbolic space of the IFS that reflects the relationship among neighboring cells, and its hyperbolic boundary with the Gromov metric is H\{o}lder equivalent to the attractor $K$. In this talk, we formulate a broad class of hyperbolic graphs, called expansive hyperbolic graphs, to capture the most essential properties from the augmented trees (e.g., the special geodesics, the bounded degree property, and the metric doubling property on the boundaries). Our main interest is $AI_\infty$-graph. Some open questions are given at the end of the talk.
