We provide many results on how to begin with the characteristic cycle (possibly in a graded, enriched form) of a given complex of sheaves and then calculate the characteristic cycles of related complexes, such as the nearby cycles and vanishing cycles of the original complex.

We provide many results on how to begin with the characteristic cycle (possibly in a graded, enriched form) of a given complex of sheaves and then calculate the characteristic cycles of related complexes, such as the nearby cycles and vanishing cycles of the original complex.
