Generic finite-parameter families of smooth vector fields have finiteness properties

About 8 years old · traced to

Let Vect∗ S2Vect^*\,S^2 be the set of all smooth vector fields on S2S^2 with isolated singular points satisfying a Łojasiewicz inequality and with finitely many cycles. A smooth vector field belongs to Vect∗ S2Vect^*\,S^2 if it has these properties.

Generic-family conjecture. Smooth vector fields met in a generic finite-parameter family belong to Vect∗ S2Vect^*\,S^2.

This asserts that generic finite-parameter families avoid smooth vector fields with nonisolated singularities, without the stated Łojasiewicz finiteness property, or with infinitely many cycles. The supplied text gives no resolution status or further context, so the conjecture is recorded as open.
