In this paper, we generalize the construction of the inverse transgression map done by Adem, A., Ruan, Y. and Zhang, B. in [A stringy product on twisted orbifold K-theory. Morfismos, 11, 33 64 (2007)] and give a dif...

In this paper,we construct an orbifold quantum cohomology twisted by a flat gerbe. Then we compute these invariants in the case of a smooth manifold and a discrete torsion on a global quotient orbifold.

代数拓扑的成就之一就是用阻碍理论的观点思考问题,它使得阻碍我们做某些事情的对象具有某种结构,从而使我们认识到无法实现的原因。要知道能不能找到一个微分方程的单值解,那就去看基本群的单值性表示。同样地,在代数几何里,要知...
