Abstract
In this paper we study Gaussian autoregression model of the form X_{n+1} = α_{n+1} X_n + W_{n+1}. It has time-inhomogeneous centered normal increments W_n and control ratios α_n. We obtained upper bounds for expectation of exponential return time to the compact [−c; c] and for expectation of the function of compressing ratios and the mentioned moment.
