Improved epsilon expansion for three-dimensional turbulence: summation of nearest dimensional singularities.
An improved epsilon expansion in the d-dimensional (d>2) stochastic theory of turbulence is constructed by taking into account pole singularities at d-->2 in coefficients of the epsilon expansion of universal quantities. Effectiveness of the method is illustrated by a two-loop calculation of the Kolmogorov constant in three dimensions.
