Quillen's vanishing André–Quillen homology conjecture for local rings

About 29 years old · traced to

Let RR be a Noetherian commutative local ring with residue field F\Bbb{F}, and write

Ds(F∣R)=Ds(F∣R;F),s≥0.D_s(\Bbb{F}|R)=D_s(\Bbb{F}|R;\Bbb{F}),\qquad s\geq 0.

Quillen's conjecture. The following are equivalent: Ds(F∣R)=0D_s(\Bbb{F}|R)=0 for s≫0s\gg 0; Ds(F∣R)=0D_s(\Bbb{F}|R)=0 for s≥3s\geq 3; and RR is a complete intersection. This conjecture characterizes local complete intersections by the vanishing of André–Quillen homology and was proven by Avramov, including in greater generality.
