Lifting Lie algebras over the residue field of a discrete valuation ring
William Browder, Jonathan Pakianathan
Studies among other things, the question of whether a Lie algebra over Z/(p^k)Z lifts to one over Z/(p^(k+1))Z. An obstruction theory is developed and examples of Fp-Lie algebras w…

Cohomology of uniformly powerful p-groups
William Browder, Jonathan Pakianathan
Studies the cohomology of p-central, powerful, p-groups with a certain extension property. These groups are naturally associated to Lie algebras. The paper develops a machinery tha…
