Chen-Ruan Cohomology and Stringy Orbifold K-Theory for Stable Almost Complex Orbifolds

Equivariant commutative stringy cohomology rings on almost complex manifolds

“…Then we get a space We next give another description of O m , which is similar to the K-theory description of the Chen-Ruan obstruction bundle obtained by Chen-Hu [10] and Hu-Wang [23], see also [18,22,25,6,16]. Consider the element (3.1).…”
