Stacked Central Configurations for the Spatial Nine-Body Problem

الملخص EN

We show the existence of the twisted stacked central configurations for the 9-body problem.

More precisely, the position vectors x1, x2, x3, x4, and x5 are at the vertices of a square pyramid Σ; the position vectors x6, x7, x8, and x9 are at the vertices of a square Π.
