A post-critically finite branched covering of the Riemann sphere may admit stable multicurves and a canonical decomposition in the sense of Pilgrim. A canonical Thurston obstructio…

Consider the classification of figures by dynamic type and topological shape, and let a totally non-hyperbolic unimodal case mean a unimodal combinatorial case that is totally non-…

Let a minimal unimodal combinatorics be a minimal combinatorial type in the unimodal region, and call it unobstructed when it is realized by the corresponding quadratic dynamical s…

Consider strongly obstructed combinatorics in the bimodal regions of topological shapes $+-+$ and $-+-$, and let $(\Sigma,\Delta)$ denote the moduli coordinates. In the unimodal ca…
