Wu, Yu-Dong and Zhang, Zhi-Hua (2006) Tangent Sphere of Edge in Tetrahedron. Research report collection, 9 (4).


In this short note, using one of Yang’s Theorems, Lin-Zhu’s conjecture for a geometric inequality with respect to the tangent sphere of the edge in tetrahedron is proved. In the final, an open problem on the n-dimension simplex is posed.
