Geography of Non-Formal Symplectic and Contact Manifolds
نویسنده
چکیده
Let (m, b) be a pair of natural numbers. For m even (resp. m odd and b ≥ 2) we show that if there is an m-dimensional non-formal compact oriented manifold with first Betti number b1 = b, there is also a symplectic (resp. contact) manifold with these properties.

On symplectic 4-manifolds and contact 5-manifolds
In this thesis we prove some results on symplectic structures on 4-dimensional manifolds and contact structures on 5-dimensional manifolds. We begin by discussing the relation between holomorphic and symplectic minimality for Kähler surfaces and the irreducibility of minimal simply-connected symplectic 4-manifolds under connected sum. We also prove a result on the conformal systoles of symplect...
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...
متن کاملThe Geography Problem for Irreducible Spin Four-manifolds
We study the geography problem for smooth irreducible simplyconnected spin four-manifolds. For a large class of homotopy types, we exhibit both symplectic and non-symplectic representatives. We also compute the Seiberg-Witten invariants of all the four-manifolds we construct.
متن کاملSymplectic fillability of toric contact manifolds
According to Lerman, compact connected toric contact 3-manifolds with a non-free toric action whose moment cone spans an angle greater than π are overtwisted, thus non-fillable. In contrast, we show that all compact connected toric contact manifolds in dimension greater than three are weakly symplectically fillable and most of them are strongly symplectically fillable. The proof is based on the...
متن کاملThe Geography of Spin Symplectic 4-manifolds
In this paper we construct a family of simply connected spin non-complex symplectic 4-manifolds which cover all but finitely many allowed lattice points (χ, c) lying in the region 0 ≤ c ≤ 8.76χ. Furthermore, as a corollary, we prove that there exist infinitely many exotic smooth structures on (2n+ 1)(S × S) for all n large enough.
