Configuration space integrals and formal smooth structures

Jianfeng Lin, Yi Xie

Watanabe disproved the 4-dimensional Smale conjecture by constructing topologically trivial $D^{4}$ -bundles over spheres and showing that they are smoothly nontrivial using configu…

The Family Seiberg-Witten Invariant and nonsymplectic loops of diffeomorphisms

Jianfeng Lin

By extending a result of Kronheimer-Mrowka to the family setting, we prove a gluing formula for the family Seiberg-Witten invariant. This formula allows one to compute the invarian…

Fixed subgroups of automorphisms of hyperbolic 3-manifold groups

Jianfeng Lin, Shicheng Wang

For fixed subgroups $F i x (ϕ)$ of automorphisms $ϕ$ on hyperbolic 3-manifold groups $π_{1} (M)$ , we observed that $rk (F i x (ϕ)) < 2 rk (π_{1} (M))$ and the constant 2 in the in…
