Abstract: Equivariant Chow rings, including Chow rings of classifying spaces of algebraic groups, appear often in nature but are difficult to compute. Like singular cohomology in topology, these Chow rings modulo a prime p carry the additional structure of unstable modules over the Steenrod algebra. We utilize this extra structure to refine estimates of equivariant Chow rings mod p. As a special case, we prove an analog of Quillen's stratification theorem, generalizing and recovering prior results of Yagita and Totaro.
