(mathematics)
If M is a matrix with positive entries, then its largest eigenvalue λ is positive and simple; moreover, there exist vectors v and w with positive components such that vM = λ v and Mw = λ w, if the inner product of v with w is 1, then the limit of λ -n times the i,j th entry of M n as n goes to infinity is the product of the i th component of w and the j th component of v.

In this analysis Potron made use of the Perron-Frobenius theorems, which at that time had been proved only for positive and irreducible non-negative matrices, but he immediately made attempts to cover also the more plausible case of decomposable input-output matrices.
