Local vanishing for toric varieties

Let X be a toric variety. We establish vanishing (and non-vanishing) results for the sheaves Ri f(*)Omega(p)((X) over tilde)(log E), where f : (X) over tilde -> X is a strong log resolution of singularities with reduced exceptional divisor E. These extend the local vanishing theorem for toric varieties in Mustata et al. (J. Inst. Math. Jussieu 19(3):801-819, 2020). Our consideration of these sheaves is motivated by the notion of k-rational singularities introduced by Friedman and Laza (Higher Du Bois and higher rational singularities, 2001). In particular, our results lead to criteria for toric varieties to have k-rational singularities, as defined in Shen et al. (On k-Du Bois and k-rational singularities, 2023).
