THE PARTITION ALGEBRA AS A CENTRALIZER ALGEBRA OF THE ALTERNATING GROUP.

In this article, we focus on the result of V.F.R. Jones which says that the partition algebra is the algebra of all transformations commuting with the action of the symmetric group on tensor products of its permutation representation. In particular, we restrict the action of the symmetric group to the action of the alternating group. In this context, we compute a basis for the centralizer algebra and show when the centralizer is isomorphic to the partition algebra. [ABSTRACT FROM AUTHOR]
