Berry-Esseen bounds and moderate deviations for the norm, entries and spectral radius of products of positive random matrices

Hui Xiao, Ion Grama, Quansheng Liu

Let $(g_{n})_{n \geq 1}$ be a sequence of independent and identically distributed positive random $d \times d$ matrices and consider the matrix product $G_{n} := g_{n} \dots g_{1}$ . Under…

Large deviation expansions for the coefficients of random walks on the general linear group

Hui Xiao, Ion Grama, Quansheng Liu

Let $(g_{n})_{n \geq 1}$ be a sequence of independent and identically distributed elements of the general linear group $G L (d, R)$ . Consider the random walk $G_n: = g_n \ldots…

A zero-one law for invariant measures and a local limit theorem for coefficients of random walks on the general linear group

Ion Grama, Jean-François Quint, Hui Xiao

We prove a zero-one law for the stationary measure for algebraic sets generalizing the results of Furstenberg [13] and Guivarc'h and Le Page [20]. As an application, we establish a…

Self-normalized Cramér type moderate deviations for stationary sequences and applications

Xiequan Fan, Ion Grama, Quansheng Liu +1

Let $(X_{i})_{i \geq 1}$ be a stationary sequence. Denote $m = ⌊ n^{α} ⌋, 0 < α < 1,$ and $k = ⌊ n / m ⌋,$ where $⌊ a ⌋$ stands for the integer part of $a .$ …
