On the Moser trick for Lie subalgebras and foliations
Ilias Ermeidis
Given a smooth deformation of a Lie subalgebra, we establish a necessary and sufficient condition for its smooth triviality and derive an analogous criterion for Lie ideals. We the…

Deformations of ideals in Lie algebras
I. Ermeidis, M. Jotz
This paper develops the deformation theory of Lie ideals. It shows that the smooth deformations of an ideal in a Lie algebra differentiate to cohomology…
