摘要翻译:
Achar最近在一个$G$-格式上导出的等变相干束范畴上引入了一族T-结构,推广了Bezrukavnikov和Deligne的反常相干T-结构。它们被称为\emph{交错}T-结构,到目前为止,它们的主要兴趣点是它们通常是自对偶的。本文研究了toric簇的$T$-等变导范畴上的这些T-结构。

英文摘要:
Achar has recently introduced a family of t-structures on the derived category of equivariant coherent sheaves on a $G$-scheme, generalizing the perverse coherent t-structures of Bezrukavnikov and Deligne. They are called \emph{staggered} t-structures, and their main point of interest so far is that they are more often self-dual. In this paper we investigate these t-structures on the $T$-equivariant derived category of a toric variety.
