Kimura-3多面体的H-表示
H-Representation of the Kimura-3 Polytope
摘要:
给定树上的基于群的马尔可夫模型,可以计算描述相关环面簇的多面体的顶点表示。然而,半空间表示并不容易计算。在$\mathbb{Z}_2$或$\mathbb{Z}_2\times\mathbb{Z}_2$的情况下,这些多面体在遗传学领域中具有应用。我们提供了一个半空间表示的$m$爪树,其中$G=\mathbb{Z}_2\times\mathbb{Z}_2$,这对应于木村3模型的演变。
英文摘要:
Given a group-based Markov model on a tree, one can compute the vertex representation of a polytope which describes the associated toric variety. The half-space representation, however, is not easily computable. In the case of $\mathbb{Z}_2$ or $\mathbb{Z}_2\times\mathbb{Z}_2$, these polytopes have applications in the field of phylogenetics. We provide a half-space representation for the $m$-claw tree where $G=\mathbb{Z}_2\times\mathbb{Z}_2$, which corresponds to the Kimura-3 model of evolution.
