Abstract:

We studied the problems about geometric inequalities for ndimensional simplex in the nonEuclid hyperbolic space and spherical space by the theory and method of distance geometry, and established the ndimensional NeubergPedoe inequalities for the volumes and edgelengths of two nsimplexes in the hyperbolic space and the spherical space.

Key words: hyperbolic space, spherical space, simplex, inequality
