Abstract [eng] In this study, the approximation of a pair of analytic functions defined on the strip {𝑠=𝜎+π‘–π‘‘βˆˆβ„‚:1/2<𝜎<1} by shifts (𝜁(𝑠+π‘–πœ),𝜁(𝑠+π‘–πœ,𝛼)), πœβˆˆβ„, of the Riemann and Hurwitz zeta-functions with transcendental 𝛼 in the interval [𝑇,𝑇+𝐻] with 𝑇27/82⩽𝐻⩽𝑇1/2 was considered. It was proven that the set of such shifts has a positive density. The main result was an extension of the Mishou theorem proved for the interval [0,𝑇], and the first theorem on the joint mixed universality in short intervals. For proof, the probability approach was applied.
