A characterisation of the n<1> + <3> form and applications to rational homology spheres
Brendan Owens, Saso Strle
We conjecture two generalisations of Elkies' theorem on unimodular quadratic forms to non-unimodular forms. We give some evidence for these conjectures including a result for deter…
Rational homology spheres and four-ball genus
Brendan Owens, Saso Strle
Using the Heegaard Floer homology of Ozsvath and Szabo we investigate obstructions to definite intersection pairings bounded by rational homology spheres. As an application we obta…
Bounds on genus and geometric intersections from cylindrical end moduli spaces
Saso Strle
In this paper we present a way of computing a lower bound for genus of any smooth representative of a homology class of positive self-intersection in a smooth four-manifold wit…
Mod 2 Seiberg-Witten invariants of homology tori
Daniel Ruberman, Saso Strle
We show that the mod 2 Seiberg-Witten invariant can be determined for a spin manifold X which has the same homology groups as the 4-torus. The value depends on the structure of the…
