Abstract:
In this paper we generalize the notion of the Taylor spectrum to modules over an arbitrary Lie algebra and study
it for finite-dimensional modules. We show that the spectrum can be described as the set of simple submodules in
the case of nilpotent and semisimple Lie algebras. We also show that this result
does not hold for solvable Lie
algebras and obtain a precise description of the spectrum in the case of Borel subalgebras of semisimple Lie
algebras.
Keywords:
Taylor spectrum, Lie algebra cohomology.
