Equivariant cohomology of torus orbifolds

Alastair Darby, Shintaro Kuroki and Jongbaek Song

We calculate the integral equivariant cohomology, in terms of generators and relations, of locally standard torus orbifolds whose odd degree ordinary cohomology vanishes. We begin by studying GKM-orbifolds, which are more general, before specialising to half-dimensional torus actions.
