Cohomology and deformations of the infinite dimensional filiform Lie algebra m_2

Alice Fialowski, Friedrich Wagemann

Denote $\fm_2$ the infinite dimensional $\mathbb{N}$-graded Lie algebra defined by the basis $e_i$ for $i\ge 1$ and by relations $[e_1,e_i]=e_{i+1}$ for all $i\ge 2$, $[e_2,e_j]=e_{j+2}$…
