Abstract
Let m, n ∈ ℕ, and V be an m-dimensional vector space over a field F of characteristic 0. Let U = F ⊕ V and R n be the rook monoid. In this paper, we construct a certain quasi-idempotent in the annihilator of U ⊗n in FR n , which comes from some one-dimensional two-sided ideal of rook monoid algebra. We show that the two-sided ideal generated by this element is indeed the whole annihilator of U ⊗n in FR n .
