N2 - Nonequilibrium domain growth in a system with a nonconserved order parameter is considered for power-law correlated initial conditions, [(r)(0)]r-(d-), appropriate to, e.g., a quench to the ordered phase from the critical point (=2-). The long-range correlations are shown to be relevant (in the renormalization-group sense), and lead to a new scaling function for the structure factor, provided that exceeds a critical value. In this regime (which includes =2-) the autocorrelation function A(t)==[(r,t)(r,0)] has the asymptotic behavior A(t)t-(d-)/4.
