Orbifold Cohomology Reloaded
نویسندگان
چکیده
We give a review of Chen-Ruan orbifold cohomology (and its cousin stringy cohomology) but starting with a reformulation, due to JarvisKaufmann-Kimura, which simplifies the original definitions and proofs by removing any reference to complex curves. We explain the relationship between the two approaches and describe their connection to other areas.

The Chen-ruan Orbifold Cohomology of Weighted Projective Spaces
Chen and Ruan [6] defined a very interesting cohomology theoryChen-Ruan orbifold cohomology. The primary objective of this paper is to compute the Chen-Ruan orbifold cohomology of the weighted projective spaces, one of the most important space used in physics. The classical tools (orbifold cohomology defined by Chen and Ruan, toric varieties, the localization technique) which have been proved t...

متن کاملThe Orbifold Cohomology Ring of Simplicial Toric Stack Bundles
We compute the orbifold cohomology ring of the simplicial toric stack bundles. We give an example to show that the ordinary cohomology ring of the crepant resolution of a simplicial toric stack bundle is not necessarily isomorphic to its orbifold cohomology ring.
متن کاملOrbifold Cohomology of the Symmetric Product
Chen and Ruan’s orbifold cohomology of the symmetric product of a complex manifold is calculated. An isomorphism of rings (up to a change of signs) H∗ orb (Xn/Sn; C) ∼= H∗(X ; C) between the orbifold cohomology of the symmetric product of a smooth projective surface with trivial canonical class X and the cohomology of its Hilbert scheme X [n] is obtained, yielding a positive answer to a conject...
