WebA second example of mathematical interest is the problem of computing thevolumeof the Birkhoff polytope. For a given dimension n, the Birkhoff polytope is the set of all doubly stochastic n n matrices (or the convex hull of all permutation matrices). This object plays a prominent role in alge-braic geometry, probability, and other fields. WebAug 24, 2024 · The Birkhoff polytope B is defined as the convex hull of the n! permutation matrices. That means the n × n matrices with all zeros except for exactly one 1 in each row and column. Equivalently B is the set of nonnegative matrices with all row and column sums equal to 1. In this case the affine subspace is defined as. The Birkhoff polytope Bn (also called the assignment polytope, the polytope of doubly stochastic matrices, or the perfect matching polytope of the complete bipartite graph $${\displaystyle K_{n,n}}$$ ) is the convex polytope in R (where N = n ) whose points are the doubly stochastic matrices, i.e., the n × n matrices whose … See more Vertices The Birkhoff polytope has n! vertices, one for each permutation on n items. This follows from the Birkhoff–von Neumann theorem, which states that the extreme points of … See more • Birkhoff algorithm • Permutohedron • Stable matching polytope See more • The Birkhoff polytope is a special case of the transportation polytope, a polytope of nonnegative rectangular matrices with given row and column sums.
