Let A be a complex diagonalizable matrix with two distinct nonzero eigenvalues λ and μ, the Yang-Baxter-like matrix equation AXA = XAX is reconsidered. We correct and improve the results in Shen et al ...
Let Γ denote the algebra of all bounded infinite matrices on c, the space of convergent sequences, Δ the subalgebra of Γ consisting of lower triangular matrices. It is well known that, if H is any ...
