[en] In four-dimensional lattice gauge theory without quarks the lowest particle states in the strong coupling region correspond to a spin zero and a spin two glueball. They are degenerate in the lowest order of the strong coupling expansion. There exists an effective transfer matrix, acting in the lowest order eigenspace, whose eigenvalues are identical with the corresponding ones of the full transfer matrix to all orders in the strong coupling expansion. It is constructed here up to the 8sup(th) nontrivial order for different gauge groups. Diagonalization yields the energy-momentum dispersion relations for glueball states. (orig.)
