振荡中间生长群

Groups of Oscillating Intermediate Growth

Martin Kassabov, Igor Pak

摘要:

本文构造了一类不可数的中间增长的有限生成群,并给出了一类新的增长函数。这些函数可以在下限和上界之间有很大的振荡,两者都来自广泛的函数类。特别地,我们可以使增长在$e^{n^a}$和任何指定函数之间振荡,如所期望的那样快速地增长。我们的构造是建立在任何一个Grigorchuk群的中间增长之上的,并且是置换圈积极限的一个变化。

英文摘要:

We construct an uncountable family of finitely generated groups of intermediate growth, with growth functions of new type. These functions can have large oscillations between lower and upper bounds, both of which come from a wide class of functions. In particular, we can have growth oscillating between $e^{n^a}$ and any prescribed function, growing as rapidly as desired. Our construction is built on top of any of the Grigorchuk groups of intermediate growth, and is a variation on the limit of permutational wreath product.
