Line tangents to four triangles in three-dimensional space
Hervé Brönnimann, Olivier Devillers, Sylvain Lazard +1
We investigate the lines tangent to four triangles in R^3. By a construction, there can be as many as 62 tangents. We show that there are at most 162 connected components of tangen…

The number of transversals to line segments in R^3
Hervé Brönnimann, Hazel Everett, Sylvain Lazard +2
We completely describe the structure of the connected components of transversals to a collection of n line segments in R^3. We show that n>2 arbitrary line segments in R^3 admit 0,…
