algebraic geometry中的球面子范畴
Spherical subcategories in algebraic geometry
摘要:
研究了具有二维分次自同态代数的三角范畴中的对象。给定这样一个对象,我们证明了存在唯一的极大三角化子范畴,其中对象是球形的。这个一般结果,然后适用于代数几何。
英文摘要:
We study objects in triangulated categories which have a two-dimensional graded endomorphism algebra. Given such an object, we show that there is a unique maximal triangulated subcategory, in which the object is spherical. This general result is then applied to algebraic geometry.
