An ergodic theorem for permanents of oblong matrices
... Remark 5. The aforementioned works [BK, KK, RW] consider sequences of matrices where the number of rows m is allowed to depend on the number of columns n. This more general situation cannot be handled with our technique, at least without further assumptions. 3. An Ergodic Theorem for Symmetric Means ...

REDUCING THE ADJACENCY MATRIX OF A TREE
... Let S E be any set of 1(T ) disjoint edges, and let X be the set of vertices incident with the edges in S . By the disjointness of S , jX j = 2 1. Let A0 = A[X jX ] be the principal submatrix of A whose rows and columns correspond to X . To establish (4), it suces to show that A0 has full rank. ...

Systems of Linear Equations in Fields
... 2R2 +R1 It follows that the only solution of the system is (0, 0). 3. Elementary and Admissible Row Operations Some row operations are clearly useful in solving systems of equations, and some are clearly useless (such as multiplying a row by zero). But in general, it is not always easy to distinguis ...

Pivoting for LU Factorization
... by a permutation matrix will result in the swapping of rows while right multiplication will swap columns. For example, in order to swap rows 1 and 3 of a matrix A, we right multiply by a permutation matrix P , which is the identity matrix with rows 1 and 3 swapped. To interchange columns 1 and 3 of ...
