Description
We construct simple analytical solutions of RG equations for the running couplings $\alpha_s$ and $y_{top}$ in the asymptotic regime. These solutions have explicit form, contain only logarithms and no special functions and subsequently sum up the leading, subleading, etc logarithms in all orders of PT. While the effect of $y_{top}$ on the running of $\alpha_s$ happens to be negligible, the role of $\alpha_s$ on the running of $y_{top}$ is essential, the account of higher orders gives a noticeable contribution.
