The generic-path conjecture for traversing vector fields

About 12 years old · traced to

Let XX be a compact smooth manifold with boundary, and let v0v_0 and v1v_1 be traversing vector fields satisfying the properties stated in Corollary 5.2, in particular boundary genericity with ∂3X(vi)=∅\partial_3X(v_i)=\emptyset.

Generic-path conjecture. Given v0v_0 and v1v_1, there is a one-parameter family of traversing fields {vt}t∈[0,1]\{v_t\}_{t\in[0,1]} connecting v0v_0 to v1v_1 such that ∂3X(vt)≠∅\partial_3X(v_t)\neq\emptyset for only finitely many values of tt, and for each exceptional value one has ∂4X(vt)=∅\partial_4X(v_t)=\emptyset.

This conjecture describes a generic one-parameter interpolation in which codimension-three boundary strata occur only at isolated parameters and higher degeneracies do not occur there. The supplied text gives no proof or resolution.
