| Theorem 1 We show that let S be a simplex in En, its vertex angles being αi and interior dihedral angles formed by arbitrary two side faces fi,fj of S being Qij, if mi are positive numbers (i,j= 1, 2, …, n + 1, i ≠ j), then Theorem 2 Let Ω be a simplex in Hn, its interior dihedral angles formed by arbitrary two side faces Fi, Fj of Ω being φij, if pi- be positive numbers (i, j = 1,2,…., n + 1, i ≠ j), then |
