Abstract :
The classical perturbation theory of linear systems Ax = b is extended to Kronecker product linear systems ( A ⊗ B ) x = d . Upper bounds are derived for the normwise and componentwise condition number. The nearness to singularity and the sensitivity of the condition numbers are analyzed.
