Limit Theorems for Spectra of Circulant Block Matrices with Large Random Blocks
MathematicsThis paper investigates the spectral properties of block circulant matrices with high-order symmetric (or Hermitian) blocks. We analyze cases with dependent or sparse independent entries within these blocks.

Isomorphic Operators and Functional Equations for the Skew-Circulant Algebra
Abstract and Applied Analysis, 2014 The skew-circulant matrix has been used in solving ordinary differential equations. We prove that the set of skew-circulants with complex entries has an idempotent basis. On that basis, a skew-cyclic group of automorphisms and functional equations on the
