Milnor fibers and links of local complete intersections. (English) Zbl 1304.32004

Summary: There are essentially no previously-known results which show how Milnor fibers, real links, and complex links “detect” the dimension of the singular locus of a local complete intersection. In this paper, we show how a good understanding of the derived category and the perverse \(t\)-structure quickly yields such results for local complete intersections with singularities of arbitrary dimension.
