Generalised Verma modules for the orthosymplectic Lie superalgebra osp(k|2)

Yucai Su, R. B. Zhang

Published 2009-11-04, updated 2009-12-18Version 2

The composition factors and their multiplicities are determined for generalised Verma modules over the orthosymplectic Lie superalgebra osp(k|2). The results enable us to obtain explicit formulae for the formal characters and dimensions of the finite-dimensional irreducible modules. Applying these results, we also compute the first and second cohomology groups of the Lie superalgebra with coefficients in finite-dimensional Kac modules and irreducible modules.
