Abstract
Relaxation and the dynamical transition in Huberman-Kerszberg-type models with arbitrary branching number σ and arbitrary dimension d are studied. A recursive variational method is employed to obtain the spectrum of relaxation modes. The exponent of the power-law relaxation, which occurs at low temperatures, is obtained for general σ and d. The dynamic transition is obtained by showing that the distribution of low-lying relaxation eigenvalues becomes identical to that of a homogeneous system above a critical temperature.
