WebMay 15, 2024 · In this section, we will give a precise characterization of simple restricted modules over L under certain conditions. First, we show the following lemma. Lemma 4.1 Let S be a simple L -module. Then the following conditions are equivalent: (1) S ∈ R L. (1) There exists k ∈ Z + such that the actions of L i, I i, i ≥ k on S are locally nilpotent. (1) WebThe central extensions, conformal derivations and free intermediate series modules of this class of Lie conformal algebras are determined. Moreover, we also show that these Lie conformal algebras do not have any non-trivial finite conformal modules. Consequently, these Lie conformal algebras cannot be embedded into gcN for any positive integer ...
