The no-exotic-obstructions conjecture for deformations of super Riemann surfaces

Let (U,ϑ)(\mathcal{U}, \vartheta) be an algebraic deformation of a super Riemann surface S(C,TC,)S(C, T^*_{C, -}) over AC0n\mathbb{A}^{0|n}_\mathbb{C}. Its primary obstruction ω(U,ϑ)\omega_{(\mathcal{U}, \vartheta)} is the obstruction to splitting the deformation. No-exotic-obstructions conjecture. If

ω(U,ϑ)=0,\omega_{(\mathcal{U}, \vartheta)}=0,

then (U,ϑ)(\mathcal{U}, \vartheta) is split. This conjecture asserts that deformations of super Riemann surfaces admit no higher obstructions once the primary obstruction vanishes; it was confirmed to second order, while the general case remains open.
