Title: Gorenstein ideals of codimension four.
Abstract: We explore spinor coordinates on free resolutions of
codimension four Gorenstein ideals. Our analysis of spinor coordinate
examples shows notable differences between Gorenstein ideals with 4, 6, 7,
and 8 generators compared to those with more generators. Also, we discuss
the codimension four Gorenstein ideals resulting from doubling codimension
three perfect ideals. We see, in particular, the construction of generic
doublings of almost complete intersection perfect ideals of codimension
three.
