K-regularity and normality (Chuck Weibel, Feb. 5, 2025)
Algebraic K-theory (and K-regularity) can detect geometric properties of a singular variety like X=Spec(A). We give two theorems to this effect, that K₂-regularity implies normality, and a result for local complete intersections that improves previous bounds by almost a factor of 2. This is joint work with C. Haesemeyer.
