Free multiderivations of connected subgraph arrangements
Abstract
Cuntz and Kühne introduced the class of connected subgraph arrangements $A_G$, depending on a graph $G$, and classified all graphs $G$ such that the corresponding arrangement $A_G$ is free. We extend their result to the multiarrangement case and classify all graphs $G$ for which the corresponding arrangement $A_G$ supports some multiplicity $μ$ such that the multiarrangement $(A_G,μ)$ is free.
