论文摘要
We determine a positive real number (weight), which corresponds to a vertex of a tetrahedron and it depends on the three weights which correspond to the other three vertices and an infinitesimal number $ε.$ As a limiting case, for $ε\to 0,$ the quad of the corresponding weights yields a degenerate weighted Fermat-Torricelli tree which coincides with the three neighbouring edges of the tetrahedron and在此顶点相交。
