A diffeomorphism classification of manifolds which are like projective planes
We give a complete diffeomorphism classification of 1-connected closed manifolds M with integral homology H∗(M) ∼= Z ⊕ Z ⊕ Z, provided that dim(M) 6= 4. The integral homology of an oriented closed manifold1 M contains at least two copies of Z (in degree 0 resp. dimM). IfM is simply connected and its homology has minimal size (i.e., H∗(M) ∼= Z⊕Z), then M is a homotopy sphere (i.e., M is homotopy...
متن کاملJacobi–tsankov Manifolds Which Are Not 2–step Nilpotent
There is a 14-dimensional algebraic curvature tensor which is Jacobi–Tsankov (i.e. J (x)J (y) = J (y)J (x) for all x, y) but which is not 2-step Jacobi nilpotent (i.e. J (x)J (y) 6= 0 for some x, y); the minimal dimension where this is possible is 14. We determine the group of symmetries of this tensor and show that it is geometrically realizable by a wide variety of pseudo-Riemannian manifolds...
متن کاملCurvature Homogeneous Pseudo-riemannian Manifolds Which Are Not Locally Homogeneous
We construct a family of balanced signature pseudo-Riemannian manifolds, which arise as hypersurfaces in flat space, that are curvature homogeneous, that are modeled on a symmetric space, and that are not locally homogeneous.
متن کاملExamples of singular normal complex spaces which are topological manifolds.
In case V is irreducible with singular curve C, we cannot write every oeH3(W V) as a tube. Indeed, oa = 6C4 and C4 Will meet C in a finite number of points. The trouble is similar to the above and may be overcome as follows: Let DC V be a curve meeting C transversely at a finite number of points pi,...pt. For simplicity, assume t = 1, p = pi, and let B be a small ball around p in W. We may assu...
متن کامل3-manifolds Which Are Spacelike Slices of Flat Spacetimes
We continue work initiated in a 1990 preprint of Mess giving a geometric parameterization of the moduli space of classical solutions to Einstein’s equations in (2 + 1) dimensions with cosmological constant Λ = 0 or −1 (the case Λ = +1 has been worked out in the interim by the present author). In this paper we make a first step toward the (3 + 1)-dimensional case by determining exactly which clo...
