A remark on semi-infinite cohomology
Xiao He
We extend the notion of semi-infinite cohomology of Lie algebras to include cases where the Lie algebra does not admit a semi-infinite structure but satisfies a mild condition. Our…

Classification of rank two Lie conformal algebras
Rekha Biswal, Abdelkarim Chakhar, Xiao He
We give a complete classification (up to isomorphism) of Lie conformal algebras which are free of rank two as $\C[\partial]$-modules, and determine their automorphism groups.
