Let f and g be two regular functions on U smooth affine variety. Let M be a regular holonomic DU -module. We are interested in the irregularity of the complex f+(Me g ). More precisely, we relate the irregularity number at c of the systems H k f+(Me g ) with the characteristic cycles of the systems H k (f,g)+(M).
