不具有正多项式Dehn函数的幂零群

Nilpotent groups without exactly polynomial Dehn function

Stefan Wenger

摘要:

证明了一类卡诺群的填充面积函数的增长的超二次下界。该类包含已知其Dehn函数增长不快于$n^2\log n$的组。因此,我们得到的存在性的(numerically生成的)幂零群群的Dehn函数不具有确切的多项式增长,从而我们回答了一个众所周知的问题,可能的增长率的Dehn函数的幂零群群。

英文摘要:

We prove super-quadratic lower bounds for the growth of the filling area function of a certain class of Carnot groups. This class contains groups for which it is known that their Dehn function grows no faster than $n^2\log n$. We therefore obtain the existence of (finitely generated) nilpotent groups whose Dehn functions do not have exactly polynomial growth and we thus answer a well-known question about the possible growth rate of Dehn functions of nilpotent groups.
