The superspace ring associated to V is the tensor product \\Omega of the ring S of polynomial functions on V with the exterior algebra E over V. If G is any subgroup of GL(V)\, there is a natural bigraded action of G on \\Omeg a\, and the superspace coinvariant ring SR_G is obtained by quotienting \\ Omega by the ideal generated by G-invariants with vanishing constant term. We study the structure of SR_G when G is a complex reflection group and V is its reflection representation with a special focus on type A. The theo ry of hyperplane arrangements plays an important role. Joint with Robert A narone\, Sutanay Bhattacharya\, Patty Commins\, Trevor Karn\, Satoshi Mura i\, and Andy Wilson.\n LOCATION:https://researchseminars.org/talk/MAAGC2026/2/ END:VEVENT END:VCALENDAR
