Soit S ϕ 1 une fibration elliptique sur une surface S, K3. Alors la composition S [n] πS (n) sym n ϕ n donne une fibration abélienne sur S[n]. Soit E le diviseur exceptionel de π, alors symnφπ(E) est de dimension n−1. Dans cette Note, nous démontrons la réciproque.

Let S ϕ 1 be an elliptic fibration on a K3 surface S. Then the composition S [n] πS (n) sym n ϕ n gives an Abelian fibration on S[n]. Let E be the exceptional divisor of π, then symnφπ(E) is of dimension n−1. We prove the inverse in this Note.
