Recall that a barycentric coordinate system is given with respect to a -dimensional simplex, where is no larger than the dimensional space. Given a set of scattered points, it’s possible to create a tessellation of the space by forming simplices from the points, such that any input point that lies within the convex hull of the scattered set can be expressed in terms of the enclosing simplex and its corresponding barycentric coordinates2. This can be understood as a kind of triangulated irregular network (TIN).
Only one team in the history of European club competitions have lost the first leg of a tie by a three-goal margin at home and advanced in the second. Up in the directors’ box, Evangelos Marinakis, more than an interested party on that occasion, presumably had flashbacks of Olympiakos suffering a 4-1 home defeat by Maccabi Tel Aviv in the Conference League two years ago, only to triumph 6-1 in Serbia in the second leg.
