The converse to the projective support characterization for quasi-reductive supergroups
Let be a quasi-reductive supergroup, and let . Write for the neat locus in the odd part of the Lie superalgebra, and for the support of . Support-projectivity conjecture. If
then is projective. This conjectures the converse of the preceding projective-support characterization; it is posed for quasi-reductive supergroups and is presented as an open question in the source.
