Findings
Characteristic cycle bounds decomposition numbers
New bounds for intersection cohomology decomposition
Link between D-modules and intersection cohomology
Abstract
We observe that the characteristic cycle of a D-module gives bounds for decomposition numbers of intersection cohomology complexes.
