The converse to the projective support characterization for quasi-reductive supergroups

About 6 years old · traced to

Let GG be a quasi-reductive supergroup, and let M∈Rep⁡(G)M\in\operatorname{Rep}(G). Write gneat\mathfrak{g}_{\mathrm{neat}} for the neat locus in the odd part of the Lie superalgebra, and supp⁡(M)\operatorname{supp}(M) for the support of MM. Support-projectivity conjecture. If

supp⁡(M)=gneat,\operatorname{supp}(M)=\mathfrak{g}_{\mathrm{neat}},

then MM 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.
