I finally gave spectral super-scheme an entry, briefly stating the idea.
This goes back to the observation highlighted in Rezk 09, section 2. There is some further support for the idea that a good definition of supergeometry in the spectrally derived/ context is nothing but -geometry over even periodic ring spectra. I might add some of them later.
Thanks to Charles Rezk for discussion (already a while back).
Does this relate to any grading by , or augmentation or any other such structure?
That -grading on , that’s -grading.
Indeed, by Sagave-Schlichtkrull, theorem 1.7-1.8 every connective -ring is canonically -graded.
So -geometry already is the higher analog of super-geometry, but of -graded supergeometry, not of the proper -graded supergeometry.
The remaining problem is to turn this categorified/homotopified -graded supergeometry into genuine -graded supergeometry. This is achieved by requiring an even periodiv ground -ring
I have added a brief mentioning of the corresponding concept of the spectral superpoint.
