摘要

In this talk, I will discuss forthcoming work with Matthew Ballard concerning a special family of toric varieties and their twisted forms. Using machinery from Galois cohomology and Noncommutative motives, we show that a twisted form has a $k$-rational point if and only if its derived category admits a full étale exceptional collection.
