Published 6 Sep 2018 in math.AT and math.AC | (1809.01801v3)
Abstract: We explore the constraints imposed by Poincar\'e duality on the resonance varieties of a graded algebra. For a 3-dimensional Poincar\'e duality algebra , we obtain a fairly precise geometric description of the resonance varieties .
