摘要:Given any regularly varying dislocation we measure, We identify a natural self-similar fragmentation tree as scaling limit of discrete fragmentation trees with unit edge lengths. As an application, we obtain continuum random tree limits of Aldous's beta-splitting models and Ford's alpha models for phylogenetic trees. limits of Aldous's beta-splitting, models and Ford's alpha models for phylogenetic trees. This confirms in a strong way that the whole trees row at the same speed as the mean heig...

摘要:One of the most well-known classical results for site percolation on the square lattice is the equation p(c) + p(c)* = 1. In words, this equation means that for all vaues not equal p(c) of the Parameter p. the following holds: either a.s. there is all infinite open cluster or a.s. there is an infinite closed star cluster. This result is closely related to the percolation transition being sharp: below p(c), the size of the open cluster of a given vertex is not only (a.s.) finite. but has a dist...
