摘要
We point out an example of a projective family pi : X -> S, a sub-variety V subset of X, and a pi-pseudoeffective divisor D on X for which the asymptotic multiplicity sigma(V) (D; X/S) is infinite. This shows that the divisorial Zariski decomposition is not always defined for pseudoeffective divisors in the relative setting.
