Cohomology of Lie algebras of polynomial vector fields on the line over fields of characteristic $2$

Felix V. Weinstein

For a field $\mathbb{F}$, let $L_k(\mathbb{F})$ be the Lie algebra of derivations $f(t)\frac{d}{dt}$ of the polynomial ring $\mathbb{F}[t]$, where $f(t)$ is a polynomial of degree…
