关于量子主丛的综合解释

On synthetic interpretation of quantum principal bundles

Tomasz Brzeziński

摘要:

量子主丛或主余模代数被重新解释为主丛的框架内的综合非交换微分几何。更具体地说,引入了辫状幺半范畴中的非交换主丛的概念,并证明了与向量空间范畴相反的范畴中的非交换主丛与忠实平坦的Hopf-Galois扩张相同.

英文摘要:

Quantum principal bundles or principal comodule algebras are re-interpreted as principal bundles within a framework of Synthetic Noncommutative Differential Geometry. More specifically, the notion of a noncommutative principal bundle within a braided monoidal category is introduced and it is shown that a noncommutative principal bundle in the category opposite to the category of vector spaces is the same as a faithfully flat Hopf-Galois extension.
