Remarks to the Dimension of an Atypical Irreducible Representation of the Special Lie Superalgebra sl(1,n) Hartmut Schlosser In [6] and [7] Palev gave explicit expressions for the action of the generators of the Lie superalgebra $sl(1,n)$ at an (irreducible) representation. His description of the representation space W of an atypical irreducible representation in terms of highest weights of $gl(n)$ representations give a possibility to compute the dimension of W numerically. In this paper we will proof an explicit formula for the dimension of an atypical representation of $sl(1,n)$ using numbers $H_l$ which connect with the Bernoulli numbers $B_l$.
