Parity Binomial Edge Ideals with Pure Resolutions
Peter Phelan
We provide a characterisation of all graphs whose parity binomial edge ideals have pure resolutions. In particular, we show that the minimal free resolution of a parity binomial ed…

Counting Dimensions of Tangent Spaces to Hilbert Schemes of Points
Daniel Mulcahy, Peter Phelan
In this paper we prove two results which further classify smoothness properties of Hilbert schemes of points. This is done by counting classes of arrows on Young diagrams correspon…
