- W4313258528 abstract "Let $A$ be a discrete valuation ring with generic point $eta$ and closed point $s$. We show that in a family of torsors over $operatorname{Spec}(A)$, the essential dimension of the torsor above $s$ is less than or equal to the essential dimension of the torsor above $eta$. We give two applications of this result, one in mixed characteristic, the other in equal characteristic." @default.
