Definition

A zero of a p-adic L-function at an interpolation point where the corresponding complex L-function does not vanish; such zeros arise from vanishing interpolation or Euler factors and produce anomalies in interpolation formulas, requiring derivative corrections in Iwasawa- and p-adic-analytic formulas.
