On the deformations of nilpotent Lie foliations (Q282724)

The paper is a continuation of the author's paper [C. R., Math., Acad. Sci. Paris 349, No. 5--6, 337--340 (2011; Zbl 1220.53035)]. Here he studies nilpotent (non-abelian) Lie foliations on some compact manifold and deformations of these foliations such that the model Lie group is allowed to change. More precisely, the author constructs a specific example of a nilpotent Lie foliation of any codimension on a compact manifold such that this foliation cannot be deformated into a non-nilpotent solvable Lie one (Theorem 2.2).
