由Morse 2-函数重构4-流形

Reconstructing 4-manifolds from Morse 2-functions

David T. Gay, Robion Kirby

摘要:

给定Morse 2-函数$f: X^4 \to S^2$,给出了折叠曲线和纤维的极小条件,使得$X^4$和$f$可以从附在$S^2$上的某个组合图重构.在其他方面也作了补充说明。

英文摘要:

Given a Morse 2-function $f: X^4 \to S^2$, we give minimal conditions on the fold curves and fibers so that $X^4$ and $f$ can be reconstructed from a certain combinatorial diagram attached to $S^2$. Additional remarks are made in other dimensions.
