Splitting spheres for $S^{2}$ -links in $S^{4}$

Jianfeng Lin, Yi Xie, Boyu Zhang

We prove that every smooth two-component split sphere link $L ⊔ R \subset S^{4}$ admits infinitely many smooth splitting $3$ -spheres that are topologically non-isotopic. This gene…

Flexible exponent of geometric 3-manifolds and Legendrian maps of Seifert spaces

Jianru Duan, Jianfeng Lin, Shicheng Wang +2

A classical question in quantitative topology is to bound the mapping degree $deg (f)$ in terms of its Lipchitz constant $Lip (f)$ . For a closed, orient…

Non-isotopic surfaces in $T^{4} # (S^{2} \times S^{2})$ : an example

Jianfeng Lin, Yue Wu

We prove that there exist infinitely many embedded tori with a common geometric dual in $T^{4} # (S^{2} \times S^{2})$ that are homotopic, diffeomorphic, but not isotopic to each other, ev…

Pseudo-isotopies of 3-manifolds with infinite fundamental groups

Jianfeng Lin, Yi Xie, Boyu Zhang

Suppose $Y$ is a compact, connected, oriented 3-manifold possibly with boundary, such that $π_{1} (Y)$ is infinite. Let $Diff_{\partial} (I \times Y)$ denote the group of s…
