We consider school choice problems (Abdulkadiroğlu and Sönmez, 2003) where students are assigned to public schools through a centralized assignment mechanism. We study the family of so-called rank-priority mechanisms, each ...

We investigate the behavior of finitely generated projective modules over a down-up algebra. Specifically, we show that every noetherian down-up algebra A(α,β,γ) has a non-free, stably free right ideal. Further, we compute ...

In this paper we study lift-and-project polyhedral operators defined by Lovász and Schrijver and Balas, Ceria and Cornuéjols on the clique relaxation of the stable set polytope of webs. We compute the disjunctive rank of ...

Let 0 < p < 1. The stable rank of the Banach algebra Q p ∩ H ∞ is 1 if given f 1, f 2 in Q p ∩ H ∞ such that inf zED( l f1(z)I + l f2(z)I) > 0, there exists g in Q p ∩ H ∞ such that f 1 + gf 2 is invertible in Q p ∩ H ∞. ...

We introduce a reconstruction formula that allows one to recover an N-order tensor X from a reduced set ofmulti-way compressivemeasurements by exploiting its low multilinear rank structure. It is proved that, in the matrix ...

This paper uses an approximate average percent-correct methodology to compare the ranks that would be obtained for PISA 2006 countries if the rankings had been derived from items judged by each country to be of highest ...
