Sharp Bounds on the PI Spectral Radius
In this paper some upper and lower bounds for the greatest eigenvalues of the PI and vertex PI matrices of a graph G are obtained. Those graphs for which these bounds are best possible are characterized.
متن کاملSpectral Radius of the Sampling Operator with Continuous Symbol
Abstract. Let φ(θ) ∼ ∑∞ −∞ ake ikθ (where ak is the k-th Fourier coefficient of φ) be a bounded measurable function on the unit circle T. Consider the operator Sφ(m,n) on L2(T) whose matrix with respect to the standard basis { eikθ : k ∈ Z } is given by (ami−nj )i,j∈Z. In this paper, we give upper and lower bound estimation for r(Sφ(m,n)), the spectral radius of Sφ(m,n). Furthermore, we will sh...
متن کاملOn spectral radius of strongly connected digraphs
It is known that the directed cycle of order $n$ uniquely achieves the minimum spectral radius among all strongly connected digraphs of order $nge 3$. In this paper, among others, we determine the digraphs which achieve the second, the third and the fourth minimum spectral radii respectively among strongly connected digraphs of order $nge 4$.

15 صفحه اولOn Linear Asynchronous Iterations When the Spectral Radius of the Modulus Matrix Is One on Linear Asynchronous Iterations When the Spectral Radius of the Modulus Matrix Is One
A classical result on linear asynchronous iterations states that convergence occurs if and only if the spectral radius of the modulus matrix is less than 1. The present paper shows that if one introduces very mild restrictions on the admissible asynchronous processes, one gets convergence for a larger class of matrices for which the spectral radius of the modulus matrix is allowed to be equal t...
