On Grauert-Riemenschneider vanishing for Cohen-Macaulay schemes of klt type

Jefferson Baudin, Tatsuro Kawakami, Linus Rösler

Given a Cohen-Macaulay scheme of klt type $X$ and a resolution $π : Y \to X$ , we show that $R^{1} π_{*} ω_{Y} = 0$ . We deduce that if $dim (X) = 3$ , then $X$ satisfies Grauert-Rieme…

Duality between $W_{n}$ -Cartier crystals and $Z / p^{n} Z$ -perverse sheaves

Jefferson Baudin

We generalize the results in [Bau23] to obtain a duality between $W_{n}$ -Cartier crystals and perverse $Z / p^{n} Z$ -sheaves.
