Orbifold Gromov-Witten Theory
In this article, we introduce the notion of good map and use it to establish
Gromov-Witten theory for orbifolds.Comment: Late
Twisted Orbifold K-Theory
We use equivariant methods to establish basic properties of orbifold
K-theory. We introduce the notion of twisted orbifold K-theory in the presence
of discrete torsion, and show how it can be explicitly computed for global
quotients.Comment: 30 page
Orbifold Quantum Cohomology
This is a research announcement of the theory of orbifold quantum cohomology.Comment: Revised version, adding more reference
