Abstract

We give a characterization of locally standard, Z\mathbb{Z}-equivariantly formal manifolds in general position. In particular, we show that for dimension 2n2n at least 1010, to every such manifold with labeled GKM graph Γ\Gamma there is an equivariantly formal torus manifold such that the restriction of the TnT^n-action to a certain Tn1T^{n-1}-action yields the same labeled graph Γ\Gamma, thus showing that the (equivariant) cohomology with Z\mathbb{Z}-coefficients of those manifolds has the same description as that of equivariantly formal torus manifolds.
