Bikei Module Invariants of Unoriented Surface-Links
Yewon Joung, Sam Nelson
We extend our previous work from arXiv:1903.06863 on biquandle module invariants of oriented surface-links to the case of unoriented surface-links using bikei modules. The resultin…

Biquandle Module Invariants of Oriented Surface-Links
Yewon Joung, Sam Nelson
We define invariants of oriented surface-links by enhancing the biquandle counting invariant using \textit{biquandle modules}, algebraic structures defined in terms of biquandle ac…
