Abstract
This paper investigates the transitivity of the relation defined by degeneration of finitely generated modules over an associative algebra. It is proved in this paper that if L degenerates to M and M degenerates to N, then \(L^{\oplus e}\) degenerates to \(N^{\oplus e}\) for some (but explicitly given) integer \(e>0\).
