EXOTIC SMOOTH STRUCTURES ON # (2n−1)(S 2 × S 2)
Let M be either S×S or more generally, (2n−1) connected sums of S × S. We construct a simply-connected minimal symplectic 4-manifold that is homeomorphic but not diffeomorphic to M . We also construct an infinite family of smooth 4-manifolds homemorphic but not diffemorphic to M .
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.

متن کاملExotic Differentiable Structures and General Relativity
We review recent developments in differential topology with special concern for their possible significance to physical theories, especially general relativity. In particular we are concerned here with the discovery of the existence of non-standard (“fake” or “exotic”) differentiable structures on topologically simple manifolds such as S, Rand S ×R. Because of the technical difficulties involve...
متن کاملA Fake Cusp and a Fishtail
We construct smooth 4-manifolds that are homeomorphic but not diffeomorphic to the “cusp” and the “fishtail”, which are thickened singular 2-spheres. Even though many fake smoothings of 4-manifolds are known to exists, we know little about the basic building blocks of exotic smooth manifolds. This is mainly due to the fact that we still don’t know if basic manifolds like S, S ×S, and S ×S could...
