Specifically, we show that if W is an irreducible representation of S_N whose Young diagram is a rectangle, and Y an irreduible finite dimensional representation of H(c,1,G), then the representation M=W\\otimes Y^N of H(0,c_0,N,G) can be deformed along a hyperplane in the space of parameters (k,c) passing through c_0. On the other hand, if Y is 1-dimensional and the Young diagram of W is not a rectangle, such a deformation does not exist.", "revisions": [ { "version": "v2", "updated": "2004-06-09T18:40:08.000Z" } ], "analyses": { "keywords": [ "symplectic reflection algebras", "wreath product symplectic reflection algebra", "construct finite dimensional representations", "young diagram" ], "note": { "typesetting": "LaTeX", "pages": 10, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2004math......3250E" } } }
