non-dicritical singularity

---

Definition 1.14. A foliation F of corank c on a normal variety X is called non-dicritical if for any divisor E over X with the dimension of cX (E) at most c − 1, each component of E is foliation invariant. F is dicritical if it is not non-dicritical. (pdf) (Chang 和 Chen, 2023, p. 8)
