Generating random vectors in \((\mathbb Z/ p \mathbb Z)^d\) via an affine random process. (English) Zbl 1159.65004
The work improves some results of C. Asci [J. Theor. Probab. 14, No. 2, 333–356 (2001; Zbl 1005.65007)], and continues with previous works of the first author; for example, see M. Hildebrand [Ann. Probab. 21, No. 2, 710–720 (1993; Zbl 0776.60012)]. The authors consider the random processes \(\mathbf X_{n+1}=T\mathbf X_n+\mathbf B_n\pmod p\) where \(\mathbf B_n\) and \(\mathbf X_n\) are random variables over \((\mathbb Z/p\mathbb Z)^d\) and \(T\) is a fixed \(d\times d\) integer matrix which is invertible over \(\mathbb C\). If \(T\) has no eigenvalues of modulus \(1\) over \(\mathbb C\), sufficient conditions are given to make \(\mathbf X_n\) close to uniformly distributed. In case \(T\) has a complex eigenvalue which is a root of unity, necessary conditions are given.
