Cohomology of orthosymplectic Lie superalgebra acting on λ-densities on ℝ1|n
Abstract
We compute the first differential cohomology of the orthosymplectic Lie superalgebra 𝔬𝔰𝔭(n|2) with coefficients in the superspace of weighted densities 𝔉nλ on the (1, 2)-dimensional real superspace. We explicitly give 1-cocycles spanning these cohomologies. This work is the simplest generalization of a result by Basdouri and Essayari [On cohomology of the orthosymplectic superalgebra, Acta Math. Hungar.130(1–2) (2011) 155–166].
