Cohomology of perfect Lie algebras

Dietrich Burde, Friedrich Wagemann

We study the adjoint cohomology of perfect Lie algebras over the complex numbers. For the family of perfect Lie algebras $g = sl_{2} (C) ⋉ V_{m}$ we obtain…

Deformations of the Lie algebra o(5) in characteristics 3 and 2

Sofiane Bouarroudj, Alexei Lebedev, Friedrich Wagemann

The finite dimensional simple modular Lie algebras with Cartan matrix cannot be deformed if the characteristic p of the ground field is equal to 0 or greater than 3. If p=3, the or…

Cohomology and deformations of the infinite dimensional filiform Lie algebra m_2

Alice Fialowski, Friedrich Wagemann

Denote $\fm_2$ the infinite dimensional $N$ -graded Lie algebra defined by the basis $e_{i}$ for $i \geq 1$ and by relations $[e_{1}, e_{i}] = e_{i + 1}$ for all $i \geq 2$ , $[e_{2}, e_{j}] = e_{j + 2}$ …

Cohomology and deformations of the infinite dimensional filiform Lie algebra m_0

Alice Fialowski, Friedrich Wagemann

Denote m_0 the infinite dimensional N-graded Lie algebra defined by basis e_i, i>= 1 and relations [e_1,e_i] = e_(i+1) for all i>=2. We compute in this article the bracket structur…
