چکیده

We prove Schur–Weyl duality between the Brauer algebra Bn(m) and the orthogonal group Om(K) over an arbitrary infinite field K of odd characteristic. If m is even, we show that each connected component of the orthogonal monoid is a normal variety; this implies that the orthogonal Schur algebra associated to the identity component is a generalized Schur algebra. As an application of the main result, an explicit and characteristic-free description of the annihilator of n-tensor space V ⊗n in the Brauer algebra Bn(m) is also given.

Schur-Weyl duality as an instrument of Gauge-String duality

A class of mathematical dualities have played a central role in mapping states in gauge theory to states in the spacetime string theory dual. This includes the classical Schur-Weyl duality between symmetric groups and Unitary groups, as well as generalisations involving Brauer and Hecke algebras. The physical string dualities involved include examples from the AdS/CFT correspondence as well as ...

G(`, k, d)-MODULES VIA GROUPOIDS

In this note we describe a seemingly new approach to the complex representation theory of the wreath product G o Sd where G is a finite abelian group. The approach is motivated by an appropriate version of Schur-Weyl duality. We construct a combinatorially defined groupoid in which all endomorphism algebras are direct products of symmetric groups and prove that the groupoid algebra is isomorphi...

The Envelope of Symmetry on Tensors and Characteristic Free Schur-weyl Duality

The envelope of the action of the symmetric group Sr on rank r tensors has dimension independent of the characteristic of the base field. M. Härterich proved this, using G.E. Murphy’s combinatorial basis of the Hecke algebra of Sr in order to describe an explicit basis for the the annihilator of tensor space. This leads to a proof of Schur-Weyl duality in positive characteristic, assuming the c...

8 M ay 2 00 8 SCHUR – WEYL DUALITY OVER FINITE FIELDS

We prove a version of Schur–Weyl duality over finite fields. We prove that for any field k, if k has more than r elements, then Schur– Weyl duality holds for the rth tensor power of a finite dimensional vector space V . Moreover, if dimV is at least r + 1 then the natural map kSr → EndGL(V )(V ) is an isomorphism; this isomorphism may fail if dimk(V ) is not strictly larger than r.
