However, the analysis that worked well <strong>in</strong> lower<br />
dimensions, hits a snag here:<br />
The branched double cover is s<strong>in</strong>gular,<br />
but the GLSM is smooth at those s<strong>in</strong>gularities.<br />
Hence, we’re not precisely gett<strong>in</strong>g a branched double<br />
cover; <strong>in</strong>stead, we’re gett<strong>in</strong>g someth<strong>in</strong>g slightly<br />
different.<br />
We believe the GLSM is actually describ<strong>in</strong>g<br />
a `noncommutative resolution’ <strong>of</strong> the branched double<br />
cover, as hpd implies <strong>in</strong> this case.
