Center of Twisted Graded Hecke Algebras for Homocyclic Groups

[摘要] We determine explicitly the center of the twisted graded Hecke algebras associated to homocyclic groups. Our results are a generalization of formulas by M. Douglas and B. Fiol in [ J. High Energy Phys. 2005 (2005), no. 9, 053, 22 pages].
