素域上仿射变换群的谱隙

Spectral gap in the group of affine transformations over prime fields

Elon Lindenstrauss, Peter P. Varju

摘要:

研究了F_p^d与SL_d(F_p)的半直积上的随机游动.我们根据投影到线性部分SL_d(F_p)的谱隙来估计谱隙。这个问题是由欧几里得空间的等距群中的一个类似物激发的,它可以应用于自相似测度的光滑性。

英文摘要:

We study random walks on the semi-direct product of F_p^d and SL_d(F_p). We estimate the spectral gap in terms of the spectral gap of the projection to the linear part SL_d(F_p). This problem is motivated by an analogue in the isometry group of Euclidean space, which have application to smoothness of self-similar measures.
