Idea

In microlocal sheaf theory one generalizes the concepts of microlocal analysis, such as the wave front set of a distributions, to sheaf theory, notably to a concept of microsupport? of a sheaf on a smooth manifold, as a subset of the cotangent bundle.

This microlocal point of view was then extended to sheaf theory by Kashiwara-Schapira 82, Kashiwara-Schapira 82) who introduced the notion of microsupport? of sheaves giving rise to microlocal sheaf theory (see Schapira 17). Beware that some authors still use the term “microlocal analysis” for this sheaf theoretic concept.

References

The generalization of the concepts of microlocal analysisto microlocal sheaf theory via the concept of microsupport? of sheaves was introduced in spring
