Using the representation for renormalization group functions in terms of nonsingular integrals, we calculate the dynamical critical exponents in the model of critical dynamics of ferromagnets in the fourth order of the $\varepsilon$-expansion. We calculate the Feynman diagrams using the sector decomposition technique generalized to critical dynamics problems.
Keywords: renormalization group, $\varepsilon$-expansion, multiloop diagram, critical parameter.
