A variation on local trilinear form
Abstract
Let F be a p-adic field and M the subgroup of GL23(F) consisting of triples with equal determinants. For each unitary principal series L-packet of M whose central character is trivial on the diagonal F×, we determine its unique member distinguished by the diagonal GL2(F).
