An improved $\text{eps}$ expansion for three-dimensional turbulence: summation of nearest dimensional singularities

An improved $\text{eps}$ expansion in the $d$-dimensional ($d>2$) stochastic theory of turbulence is constructed by taking into account pole singularities at $d\to 2$ in coefficients of the $\text{eps}$ expansion of universal quantities. Effectiveness of the method is illustrated by a two-loop calculation of the Kolmogorov constant in three dimensions.
