Generalised permutation
WebAug 14, 2024 · Fast array permutation (generalised tensor transpose) in Armadillo (C++) I have a project which involves a lot of permutations on 3D arrays ( arma::Cube ). In particular, the required permutation is the interchange of columns by slices. In Matlab this is efficiently calculated by permute (cube, [1,3,2]) and in … WebIf is a permutation group of degree , then the permutation representation of is the linear representation of ρ : G → GL n ( K ) {\displaystyle \rho \colon G\to \operatorname {GL} …

In mathematics, a generalized permutation matrix (or monomial matrix) is a matrix with the same nonzero pattern as a permutation matrix, i.e. there is exactly one nonzero entry in each row and each column. Unlike a permutation matrix, where the nonzero entry must be 1, in a generalized permutation matrix the … See more An invertible matrix A is a generalized permutation matrix if and only if it can be written as a product of an invertible diagonal matrix D and an (implicitly invertible) permutation matrix P: i.e., See more A signed permutation matrix is a generalized permutation matrix whose nonzero entries are ±1, and are the integer generalized permutation matrices with integer inverse. See more Monomial representations Monomial matrices occur in representation theory in the context of monomial representations. A monomial representation of a … See more • If a nonsingular matrix and its inverse are both nonnegative matrices (i.e. matrices with nonnegative entries), then the matrix is a generalized … See more One can generalize further by allowing the entries to lie in a ring, rather than in a field. In that case if the non-zero entries are required to be units in the ring, one again obtains a group. On the other hand, if the non-zero entries are only required to be non-zero, but not … See more WebMar 26, 2005 · The description of B-type D-branes on a tensor product of two N = 2 minimal models in terms of matrix factorisations is related to the boundary state description in conformal field theory. As an application we show that the D0- and D2-brane for a number of Gepner models are described by permutation boundary states. In some cases …
• For the generalized symmetric group is exactly the ordinary symmetric group: • For one can consider the cyclic group of order 2 as positives and negatives () and identify the generalized symmetric group with the signed symmetric group. WebJan 18, 2014 · The question thus becomes a combinatorical one I believe. you never stated the non-zero entries must be 1. In generalized permutation matrices the entries need not be 1. I think the value 9 for the case ( n, k) = ( 3, 2) is wrong and should be 6 instead. I updated my post correspondingly.
