Abstract: Let$G_1\otimes G_2$and$G_1\times G_2$be the coalescence and Cartesian product of two connected m-uniform hypergraphs$G_1$and$G_2$respectively. We will give explicit formulas for the stabilizing indices and cyclic indices of$G_1\otimes G_2$and$G_1\times G_2$in terms of those of$G_1$and$G_2$or the invariant divisors of their incidence matrices over$Z_m$,respectively.
