Department of Mathematics Schedler, Travis C2 C2 ∼= C4. We show that the quotient C[superscript 4]/G admits a symplectic resolution for G = Q[subscript 8] x [subscript Z/2]D[subscript 8] < Sp[subscript 4](C). Here Q[subscript 8] is the quaternionic group of order eight and D[subscript 8] is the dihedral group of order eight, and G is the quotient of their direct product which identifies the nontrivial central elements −Id of each. It is equipped with the tensor product representation C[superscript 2] ⊠ C[superscript 2] ≅ C[superscript 4]. This group is also naturally a subgroup of the wreath product group Q[superscript 8][subscript 2] ⋊ S[subscript 2] < Sp[subscript 4](C). We compute the singular locus of the family of commutative spherical symplectic reflection algebras deforming C[superscript 4]/G. We also discuss preliminary investigations on the more general question of classifying linear quotients V/G admitting symplectic resolutions. 2016-10-24T16:50:25Z 2016-10-24T16:50:25Z 2012-04 2012-08 2016-08-18T15:23:52Z Article http://purl.org/eprint/type/JournalArticle 0025-5874 1432-1823 http://hdl.handle.net/1721.1/104945 Bellamy, Gwyn, and Travis Schedler. “A New Linear Quotient of C 4 Admitting a Symplectic Resolution.” Mathematische Zeitschrift 273.3–4 (2013): 753–769. en http://dx.doi.org/10.1007/s00209-012-1028-6 Mathematische Zeitschrift Article is made available in accordance with the publisher's policy and may be subject to US copyright law.
