Grid homology for spatial graphs and a Künneth formula of connected sum
Hajime Kubota
In this paper, we research the grid homology for spatial graphs with cut edges. We show that the grid homology for spatial graph is trivial if has sinks, sources, or cut ed…

Some properties of grid homology for MOY graphs
Hajime Kubota
Grid homology for MOY graphs is immediately defined from grid homology for transverse spatial graphs developed by Harvey and O'Donnol in 2017. We studied some properties of grid ho…
