The Geography Problem for 4–manifolds with Specified Fundamental Group
نویسنده
چکیده
Fix a group G and let M(G) denote the class of closed oriented manifolds with π1(M) ∼= G. The geography of M(G) is the set of integer pairs {(σ(M), χ(M)) | M ∈ M(G)}, where σ and χ denote the signature and Euler characteristic. This paper explores general properties of the geography of M(G) and undertakes an extended study of M(Zn).

On the Geography and Botany of Irreducible 4-manifolds with Abelian Fundamental Group
The geography and botany of smooth/symplectic 4-manifolds with cyclic fundamental group are addressed. For all the possible lattice points which correspond to non-spin manifolds of negative signature and a given homeomorphism type, an irreducible symplectic manifold and an infinite family of pairwise non-diffeomorphic non-symplectic irreducible manifolds are manufactured. In the same fashion, a...
متن کاملGeography and Botany of Irreducible Nonspin Symplectic 4-manifolds with Abelian Fundamental Group
The geography and botany problems of irreducible nonspin symplectic 4-manifolds with a choice of fundamental group from {Zp,Zp⊕Zq,Z,Z⊕Zp,Z⊕Z} are studied by building upon the recent progress obtained on the simply connected realm. Results on the botany of simply connected 4-manifolds not available in the literature are extended.
متن کاملThe Geography of Symplectic 4-manifolds with an Arbitrary Fundamental Group
In this article, for each finitely presented group G, we construct a family of minimal symplectic 4-manifolds with π1 = G which cover most lattice points (x, c) with x large in the region 0 ≤ c < 9x. Furthermore, we show that all these 4-manifolds admit infinitely many distinct smooth structures.
متن کاملSmall Irreducible Symplectic 4-manifolds with Abelian Non-cyclic Fundamental Group
there exists a symplectic irreducible 4-manifold X with π1(X) = G and (c 2 1(X), χh(X)) = (c, χ). The characteristic numbers are given in terms of χh = 1/4(e+σ) and c 2 1 = 2e+3σ, where e is the Euler characteristic of the manifold X and σ its signature. To describe conditions under which smooth 4-manifolds are unique has been a theme in 4-manifold theory for quite some time. Besides its role i...

In this paper, we exploit a subtle indeterminacy in the definition of the spherical Kervaire–Milnor invariant which was discovered by R. Stong to construct non–spin 4–manifolds with even intersection form and prescribed signature. As an important ingredient of the proof of their π1–negligible embedding theorem, M. Freedman and F. Quinn introduced in [4] a Z2–valued invariant of an immersed sphe...
