چکیده

7 Given an n × n matrix, its principal rank characteristic sequence is a sequence of 8 length n + 1 of 0s and 1s where, for k = 0, 1, . . . , n, a 1 in the kth position indicates 9 the existence of a principal submatrix of rank k and a 0 indicates the absence of such 10 a submatrix. The principal rank characteristic sequences for symmetric matrices over 11 various fields are investigated, with all such attainable sequences determined for all n 12 over any field with characteristic 2. A complete list of attainable sequences for real 13 symmetric matrices of order 7 is reported. 14

The principal rank characteristic sequence over various fields

Given an n × n matrix, its principal rank characteristic sequence is a sequence of length n + 1 of 0s and 1s where, for k = 0, 1, . . . , n, a 1 in the kth position indicates the existence of a principal submatrix of rank k and a 0 indicates the absence of such a submatrix. The principal rank characteristic sequences for symmetric matrices over various fields are investigated, with all such att...

The enhanced principal rank characteristic sequence over a field of characteristic 2

The enhanced principal rank characteristic sequence (epr-sequence) of an n× n symmetric matrix over a field F was recently defined as `1`2 · · · `n, where `k is either A, S, or N based on whether all, some (but not all), or none of the order-k principal minors of the matrix are nonzero. Here, a complete characterization of the epr-sequences that are attainable by symmetric matrices over the fie...

On the Principal Permanent Rank Characteristic Sequences of Graphs and Digraphs

The principal permanent rank characteristic sequence is a binary sequence r0r1 · · · rn where rk = 1 if there exists a principal square submatrix of size k with nonzero permanent and rk = 0 otherwise, and r0 = 1 if there is a zero diagonal entry. A characterization is provided for all principal permanent rank sequences obtainable by the family of nonnegative matrices as well as the family of no...

The Enhanced Principal Rank Characteristic Sequence for Hermitian Matrices

The enhanced principal rank characteristic sequence (epr-sequence) of an n×n matrix is a sequence `1`2 · · ·`n, where each `k is A, S, or N according as all, some, or none of its principal minors of order k are nonzero. There has been substantial work on epr-sequences of symmetric matrices (especially real symmetric matrices) and real skew-symmetric matrices, and incidental remarks have been ma...

On p-semilinear transformations

In this paper, we introduce $p$-semilinear transformations for linear algebras over a field ${bf F}$ of positive characteristic $p$, discuss initially the elementary properties of $p$-semilinear transformations, make use of it to give some characterizations of linear algebras over a field ${bf F}$ of positive characteristic $p$. Moreover, we find a one-to-one correspondence between $p$-semiline...
