Voorbeelden van tetrahedron

• In the first case, the tetrahedron is skinny, and we distinguish five types depending on how its vertices cluster along the line.

• Think of two congruent tetrahedrons made of differently pliable material.

• We can even use (3.10) to define the local spaces for any diffeomorphic image of a tetrahedron.

• We shall identify these curves, which might be thought of as forming a supporting framework for the tetrahedron.

• The upper bound is based on a new charging scheme which assigns each tetrahedron of minimum volume to one of its four faces.

• We normalize by scaling tetrahedra to unit diameter.

• The sliver is the only type of small volume tetrahedron whose circumradius over shortest edge length ratio does not grow with decreasing volume.

• In particular, the analysis is based on the singularities of these tetrahedra.
