Let $I$ be the Hochschild-Kostant-Rosenberg isomorphism and let $I'$ be its modification obtained by composing it with wedging by $\operatorname{td}_X^{1/2}$. For a homogeneous ele…

Let $X$ be a compact smooth space. The modified Hochschild-Kostant-Rosenberg maps $I^K$ and $I_K$ are the maps obtained by twisting the Hochschild-Kostant-Rosenberg isomorphism by…

Let $A$ be an $\mathbb F_p$-algebra and let $X/A$ be a scheme. Consider the Hochschild-Kostant-Rosenberg spectral sequence for $X/A$, with differentials denoted by $d_r$. Power-of-…
