均匀增长率

Uniform growth rate

Kasra Rafi, Jing Tao

摘要:

在一个进化系统中,突变规则本质上是局部的,$m$突变后可能的结果数是$m$的指数函数,但其速率只取决于规则集,而不是原始对象的大小。我们应用这一原则,找到一个统一的上界的增长率的某些群体,包括映射类群。我们还发现了一个统一的上界的增长率的同伦类的三角剖分的定向表面,可以从一个给定的三角剖分使用$m$对角翻转。

英文摘要:

In an evolutionary system in which the rules of mutation are local in nature, the number of possible outcomes after $m$ mutations is an exponential function of $m$ but with a rate that depends only on the set of rules and not the size of the original object. We apply this principle to find a uniform upper bound for the growth rate of certain groups including the mapping class group. We also find a uniform upper bound for the growth rate of the number of homotopy classes of triangulations of an oriented surface that can be obtained from a given triangulation using $m$ diagonal flips.
