Abstract
We consider E(x)x(k + 1) = F(k)x(k), \(k \in Z^+_0\) , where E(k) and F(k) are real square matrices of order n, not necessarily invertible. Assuming the regularity of the matrix pencils \(\lambda E(x) - F(k)x(k), k \in Z^+_0\) and the existence of a nonzero common eigenvector of the family of n × n real matrices { Ê \((k) = [\alpha_kE(k) - F(k)]^{-1} E(k), \alpha_k \in R, k \in Z^+_0\)}, we will obtain a solution to the above descriptor system. We also analyse a particular case related with a positive equation — the closed dynamic Leontief model.
