Abstract
The asymptotics of decay of correlations of spins in the ANNNI model on an (v+1)-dimensional lattice for high temperatures is shown to consist of exponentionally decaying oscillations. The problem of describing the asymptotics is reduced to the spectral analysis of one-particle states of a corresponding infinite-particle Hamiltonian.
