On grid homology for lens space links: combinatorial invariance and integral coefficients
arXiv (Cornell University)(2021)
摘要
Following the approach to grid homology of links in $S^3$, we prove combinatorially that the grid homology of links in lens spaces defined by Baker, Grigsby, and Hedden is a link invariant. Further, using the sign assignment defined by Celoria, we prove that the generalization of grid homology to integral coefficients is a link invariant.
