| | <正> A few years ago, at the conference on metric geometry held in Michigen, K. B. Stolarsky posed a problem (cf. [1], problem 1) which challenges some classical methods of distance geometry. Let T be a tetrahedron whose base is a triangle, with edge-lengths a, b, c, and 【作者单位】:Institute of Mathematical Sciences;Ghengdu Branch;Academia Sinica;Institute of Mathematical Sciences;Ghengdu Branch;Academia Sinica 【DOI】:cnki:ISSN:1001-6538.0.1985-11-001 【正文快照】: A few years ago,B.Stolars冲Poseda at the eonfereneeproblem(0f,[i],on metrie geometryprobleml)w址。h held纽孤ehigen,K.必心eng明:om必e妞ssiealmethods吐distanee geometry.Let T be atetra’hedron whose base isa通,刀,C bethe lengths oftheedgesopp6sitetnred that |
