New symplectic 4-manifolds with nonnegative signature
نویسندگان
چکیده
We construct new families of symplectic 4-manifolds with nonnegative signature that are interesting with respect to the geography problem. In particular, we construct an irreducible symplectic 4-manifold that is homeomorphic to mCP#mCP for each odd integer m satisfying m ≥ 49.

Spin symplectic 4-manifolds near Bogomolov-Miyaoka-Yau line
We construct the first known family of simply connected spin symplectic 4-manifolds Mk satisfying c 2 1 (Mk)/χh(Mk) → 9 as k → ∞. Using Mk, we also construct many other new spin symplectic 4-manifolds with nonnegative signature.

We construct a new family {Kn} of simply connected symplectic 4-manifolds with the property c1(Kn)/χh(KN ) → 9 (as n → ∞).
متن کاملOn 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...

For each pair (e, σ) of integers satisfying 2e + 3σ ≥ 0, σ ≤ −2, and e + σ ≡ 0 (mod 4), with four exceptions, we construct a minimal, simply connected symplectic 4-manifold with Euler characteristic e and signature σ. We also produce simply connected, minimal symplectic 4-manifolds with signature zero (resp. signature −1) with Euler characteristic 4k (resp. 4k + 1) for all k ≥ 46 (resp. k ≥ 49).
متن کاملSymplectic 4-manifolds with Arbitrary Fundamental Group near the Bogomolov-miyaoka-yau Line Scott Baldridge and Paul Kirk
In this paper we construct a family of symplectic 4–manifolds with positive signature for any given fundamental group G that approaches the BMY line. The family is used to show that one cannot hope to do better than than the BMY inequality in finding a lower bound for the function f = χ+ bσ on the class of all minimal symplectic 4-manifolds with a given fundamental group.
