Nonunital E-infinity structure conjecture for the first derivative spectrum

About 3 years old · traced to

Let F ⁣:J→SF \colon \mathcal{J} \to \mathcal{S} be lax symmetric monoidal, and let Θ1F\Theta^1F denote its first derivative spectrum. First derivative multiplication conjecture. The spectrum Θ1F\Theta^1 F is a nonunital E∞E_\infty-ring spectrum.

This is presented as a consequence that would follow from the preceding untwisted multiplication conjecture, using the non-equivariant equivalence between the twisted derivative and an iterated loop of the derivative. The claim concerns the existence of coherent commutative multiplication without a unit on the first derivative spectrum.
