الوصف: We define coarse skeletons of graphs in terms of two constants. We introduce the notion of coarse bottlenecking in graphs and show how it can guarantee that a skeleton resembles (up to quasi-isometry) the original graph. We show how notions similar to the coarse skeleton have been previously used to classify some coarse families of graphs. We explore the properties of a coarse skeleton and of combinations of skeletons. We show how these tools can be used to simplify the structure of graphs that have an excluded asymptotic minor, reducing it to a skeleton of the original containing at most a 3-fat minor, we give an example to show that a similar result does not hold for 2-fat minors.
