Doubly stochastic circulant matrices
Discrete Mathematics, 1991 Let \(P_ n\) be the circulant matrix of order \(n\) with the first row of the form \((0,1,0,\ldots,0)\). Let \(G^ 2_ n\) denote the set of all \(n\times n\) doubly stochastic matrices of the form \(\alpha_ nI_ n+\beta P_ n+\gamma_ nP_ n^ 2\), and let \(\mu_ n\) denote the minimum value of the permanent on \(G^ 2_ n\). In the note the lower bound for \(\

Journal of Function Spaces, 2014 Improved estimates for spectral norms of circulant matrices are investigated, and the entries are binomial coefficients combined with either Fibonacci numbers or Lucas numbers. Employing the properties of given circulant matrices, this paper improves the

Highly symmetric generalized circulant permutation matrices
, 2008 In this paper we investigate generalized circulant permutation matrices of composite order. We give a complete characterization of the order and the structure of symmetric generalized k-circulant permutation matrices in terms of circulant and ...

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

Algorithms for Finding Inverse of Two Patterned Matrices over Zp
Abstract and Applied Analysis, 2014 Circulant matrix families have become an important tool in network engineering. In this paper, two new patterned matrices over Zp which include row skew first-plus-last right circulant matrix and row first-plus-last left circulant matrix are presented ...

Analysis of the Structured Perturbation for the BCSCB Linear System
Abstract and Applied Analysis, 2015 Circulant and block circulant type matrices are important tools in solving networked systems. In this paper, based on the style spectral decomposition of the basic circulant matrix and the basic skew circulant matrix, the block style spectral ...
