Let G be connected uniform hypergraph and let be the adjacency tensor of G. The stabilizing index of G is exactly the number of eigenvectors of associated with the spectral radius, and the cyclic index of G is exactly the number of eigenvalues of with modulus equal to the spectral radius. Let and be the coalescence and Cartesian product of connected m-uniform hypergraphs and respectively. In this paper, we give explicit formulas for the stabilizing indices and cyclic indices of and in terms of those of and or the invariant divisors of their incidence matrices over , respectively.
