In the case at hand\, this procedure relies on a study of the category of GL(2)- equivariant perverse sheaves on the moduli space of homogeneous cubics in two variables\, which is perhaps of independent interest. Specifically\, w e find the Fourier transform and the microlocalization of the simple objec ts in this category\, and convert that into information about the Aubert i nvolution and stable distributions attached to Arthur packets. This is joi nt work with Andrew Fiori and Qing Zhang\, based on earlier joint work wit h Andrew Fiori\, Ahmed Moussaoui\, James Mracek and Bin Xu\, which is base d on earlier work by David Vogan\, sadly\, not joint.\n LOCATION:https://researchseminars.org/talk/MITLie/3/ END:VEVENT END:VCALENDAR
