%0 Journal Article %T Realizing the local Weil representation over a number field %A Gerald Cliff %A David McNeilly %J Mathematics %D 2009 %I arXiv %X We show that the Weil representation of the symplectic group Sp(2n,F), where F is a non-archimedian local field, can be realized over the field obtained from the rationals by adjoining the square roots of p and -p, where p is the residue characteristic of F; p is assumed to be odd. %U http://arxiv.org/abs/0904.2354v1
