Partitions of the polytope of doubly substochastic matrices
In mathematics, especially in probability and combinatorics, a doubly stochastic matrix (also called bistochastic matrix) is a square matrix $${\displaystyle X=(x_{ij})}$$ of nonnegative real numbers, each of whose rows and columns sums to 1, i.e., $${\displaystyle \sum _{i}x_{ij}=\sum _{j}x_{ij}=1,}$$Thus, … See more • The product of two doubly stochastic matrices is doubly stochastic. However, the inverse of a nonsingular doubly stochastic matrix need not be doubly stochastic (indeed, the inverse is doubly stochastic iff it has … See more • PlanetMath page on Birkhoff–von Neumann theorem • PlanetMath page on proof of Birkhoff–von Neumann theorem See more Let X be a doubly stochastic matrix. Then we will show that there exists a permutation matrix P such that xij ≠ 0 whenever pij ≠ 0. … See more • Stochastic matrix • Unistochastic matrix • Birkhoff algorithm See more WebIn this paper, some inequalities for permanents and permanental minors of row substochastic matrices are proved. The convexity of the permanent function on the interval between the identity matrix and an arbitrary row substochastic matrix is also proved. In addition, a conjecture about the permanent and permanental minors of square row … proceed logistics bv
