Title:  Dimensional vanishing of the saturated de Rham-Witt complex
Abstract:  The saturated de Rham-Witt complex, introduced by Bhatt-Lurie-Mathew, is a variant of the classical de Rham-Witt complex which is expected to behave better for singular schemes.  We provide partial justification for this expectation by showing that the saturated de Rham-Witt complex satisfies dimensional vanishing even in the presence of singularities--like étale cohomology, but unlike any of de Rham, classical de Rham-Witt, and crystalline cohomology.
