Extendability over the $4$ -sphere and invariant spin structures of surface automorphisms

Weibiao Wang, Zhongzi Wang

It is known that an automorphism of $F_{g}$ , the oriented closed surface of genus $g$ , is extendable over the 4-sphere $S^{4}$ if and only if it has a bounding invariant spin structure…

Distributions of points on non-extensible closed curves in $R^{3}$ realizing maximum energies

Shiu-Yuen Cheng, Zhongzi Wang

Let $G_{n}$ be a non-extensible, flexible closed curve of length $n$ in the 3-space $R^{3}$ with $n$ particles $A_{1}$ ,..., $A_{n}$ evenly fixed (according to the arc length of $G_{n}$ ) on t…

On the realisation problem for mapping degree sets

Christoforos Neofytidis, Hongbin Sun, Ye Tian +2

The set of degrees of maps $D (M, N)$ , where $M, N$ are closed oriented $n$ -manifolds, always contains $0$ and the set of degrees of self-maps $D (M)$ always contains $0$ and $1$ . Also…
