Abstract
We investigate the second cohomology space associated with the embedding of the orthosymplectic Lie superalgebra osp(n|2) on the (1,n)-dimensional superspace R1|n in the Lie superalgebra SΨDO(n) of superpseudodifferential operators with smooth coefficients, where n=0,1,2. We show that this space is purely even and we give explicit expressions of the basis cocycles.
