In this paper, we present a new algorithm Global-DGMRES to find the Drazin inverse solution of the linear matrix equation AXB = C, where at least one of the matrices A or B is rank deficient. This ...

Let J n ( λ ) be the n × n Jordan block with a positive real eigenvalue λ and A : = J n ( λ ) ⊕ J n ( − λ ) . In this paper, we study the polynomial numerical hull of degree k, H k ( A ) , when k = 2 and k = 2 n − 1 . If 0 ≤ λ ≤ 3 2 ,

The spectral radius of a graph is the largest eigenvalue of the adjacency matrix corresponding to this graph. Let G be a graph with long pendant paths. In this note, we estimate the spectral radius of G, by obtaining appropriate upper and lower bound

The DGMRES algorithm was designed to compute the Drazin inverse solution of consistent or inconsistent linear systems A x = b , where A is a square singular matrix with arbitrary index. In this paper we compare the convergence rate of DGMRES with tha

Let X and Y be real n×m matrices. We say that X is circulant matrix majorized by Y and write X≺cY , if X=QY for some circulant doubly stochastic matrix Q∈Mn(R) . A linear operator T:Mn,m(R)⟶Mn,m(R)...
