Abstract [eng] The Riemann hypothesis (RH) says that all zeros of the Riemann zeta function 𝜁(𝑠), 𝑠=𝜎+𝑖𝑡, in the strip {𝑠∈ℂ:0<𝜎<1} lie on the line 𝜎=1/2. There are many equivalents of RH in various terms. In this paper, we propose equivalents of RH in terms of self-approximation, i.e., of the approximation of 𝜁(𝑠) by 𝜁(𝑠+𝑖𝜏), 𝜏∈ℝ, in the interval 𝜏∈[𝑇,𝑇+𝑈] with 𝑇^𝜂⩽𝑈⩽𝑇, 𝜂=1273/4033. We show that the RH is equivalent to the positivity of lower density and (with some exception for the accuracy of approximation) the density of the set of approximating shifts 𝜁(𝑠+𝑖𝜏). For the proof, a probabilistic approach and mean square estimates for 𝜁(𝑠) in short intervals are applied.
