On polynomial equations and circulant matrices

, 2006
This thesis is an exposition of the article Polynomial Equations and Circulant Matrices by Dan Kalman and James E. White. It uses circulant matrices as an alternative way for solving polynomial equations of degree less than or equal to four.

Unit group of the ring of negacirculant matrices over finite commutative chain rings

Special Matrices
Circulant matrices form an important class of matrices that have been continuously studied due to their nice algebraic structures and wide applications. In this study, we focus specifically on negacirculant matrices, which are known as extensions of the ...

A note on MDS property of circulant matrices

Journal of Discrete Mathematical Sciences & Cryptography
In 2014, Gupta and Ray proved that the circulant involutory matrices over the finite field F2m can not be maximum distance separable (MDS). This non-existence also extends to circulant orthogonal matrices of order 2d × 2d over finite fields of characteristic 2.

Eigenvectors of block circulant and alternating circulant matrices,” Res [PDF]

, 2005
. The eigenvectors and eigenvalues of symmetric block circulant ma-trices had been found, and that method is extended to general block circulant matrices. That analysis is applied to Stephen J.

QC-LDPC Codes Construction by Concatenating of Circulant Matrices as Block-Columns

International Journal of Information and Communication Technology Research, 2016
In this paper a new low complexity method for constructing binary quasi-cyclic low-density parity-check (QC-LDPC) codes is introduced. In the proposed method, each block-column of the parity check matrix H is made by a circulant matrix in a way that the ...
