Abstract
Let be an Abelian group. In this paper I characterize the -paths of weight that have the Erd\H{o}s-P\'osa property. Using this in an auxiliary graph, one can also easily characterize the -paths of weight that have the Erd\H{o}s-P\'osa property. These results also extend to long paths, that is paths of some minimum length. A structural result on zero walls with non-zero linkages will be proven as a means to prove the main result of this paper. This immediately implies that zero cycles with respect to an Abelian group have the Erd\H{o}s-P\'osa property.
