Abstract We study solution of the stochastic equation where A is a random matrix and B, X are random vectors, the law of (A, B) is given and X is independent of (A, B). The equation is meant in law, the matrix A is upper triangular, , . A sharp asymptotics of the tail of is obtained. We show that under ‘so called’ Kesten–Goldie conditions and , where or .
