The group inverse of some circulant matrices [PDF]

, 2019
We present here necessary and sufficient conditions for the invertibility of some circulant matrices that depend on three parameters and moreover, we explicitly compute the inverse. Our study also encompasses a wide class of circulant symmetric matrices.

Effective algorithms with circulant-block matrices

, 1994
Effective numerical algorithms for circulant-block matrices A whose blocks are circulant are obtained. The eigenvalues of such matrices are determined in terms of the eigenvalues of matrices of reduced dimension, and systems of linear equations involving

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 ...
