✦ Synopsis

We study the influence of quenched extended defects on the critical dynamics of the d = 3-dimensional systems with m-component non-conserved order parameter (model A dynamics). Considering defects to be correlated in ε d dimensions and randomly distributed in d -ε d dimensions we obtain reliable numerical values for the critical exponents governing divergence of the relaxation time as function of m and ε d .
