A note on generalized Perron complements of Z-matrices
The concept of the Perron complement of a nonnegative and irreducible matrix was introduced by Meyer in 1989 and it was used to construct an algorithm for computing the stationary distribution vector for Markov chains. Here properties of the generalized Perron complement of an n×n irreducible Z-matrixK are considered. First the result that the generalized Perron complements of K are irreducible...

متن کاملA note on the eigenvalues of g-circulants (and of g-Toeplitz, g-Hankel matrices)
A matrix A of size n is called g-circulant if A = [ a(r−gs) mod n ]n−1 r,s=0 , while a matrix A is called g-Toeplitz if its entries obey the rule A = [ar−gs] n−1 r,s=0. In this note we study the eigenvalues of g-circulants and we provide a preliminary asymptotic analysis of the eigenvalue distribution of g-Toeplitz sequences, in the case where the numbers {ak} are the Fourier coefficients of an...
متن کاملA Note on the Conformal Invariance of G-generalized Gradients
We consider generalized gradients in the general context of G-structures. They are natural first order differential operators acting on sections of vector bundles associated to irreducible G-representations. We study their geometric properties and show in particular their conformal invariance. 2000 Mathematics Subject Classification: Primary 53C10, 53A30, 58J60.
متن کاملA Note on Artinianess of Certain Generalized
Let ?: R0?R be a ring homomorphism and suppose that a and a0, respectively, are ideals of R and R0 such that is an Artinian ring. Let M and N be two finitely generated R-modules and suppose that (R0,m0) is a local ring. In this note we prove that the R-modules and are Artinian for all integers i and j, whenever and . Also we will show that if a is principal, then the R-modules and ...
