Indecomposable doubling for representations of the type I Lie superalgebras sl(m/n) and osp(2/2n)

چکیده
We establish that for the type I Lie superalgebras $sl(m/n)$ and $osp(2/2n)$, each Kac module admits a 1 parameter family of indecomposable double extensions. The result follows from explicit evaluation $H^1$ superalgebra cohomology valued in tensor product its dual.

Indecomposable Finite-dimensional Representations of a Class of Lie Algebras and Lie Superalgebras
The topic of indecomposable finite-dimensional representations of the Poincaré group was first studied in a systematic way by S. Paneitz ([5][6]). In these investigations only representations with one source were considered, though by duality, one representation with 2 sources was implicitly present. The idea of nilpotency was mentioned indirectly in Paneitz’s articles, but a more down-to-earth...
متن کاملRepresentations of Lie Superalgebras in Prime Characteristic I
We initiate the representation theory of restricted Lie superalgebras over an algebraically closed field of characteristic p > 2. A superalgebra generalization of the celebrated Kac-Weisfeiler Conjecture is formulated, which exhibits a mixture of p-power and 2-power divisibilities of dimensions of modules. We establish the Conjecture for basic classical Lie superalgebras.

Universally defined representations of Lie conformal superalgebras
We distinguish a class of irreducible finite representations of conformal Lie (super)algebras. These representations (called universally defined) are the simplest ones from the computational point of view: a universally defined representation of a conformal Lie (super)algebra L is completely determined by commutation relations of L and by the requirement of associative locality of generators. W...
