Complex \(D\) convergence and diagonal convergence of matrices
The author analyses several types of convergence introduced in the literature that are more restrictive than just the condition \(\rho(A) < 1\): \(D\) convergence, diagonal convergence and boundary convergence, and proves that for complex matrices of order \(n \leq 3\) they are all equivalent.
