%0 Journal Article %T Path Ideals of Weighted Graphs %A Bethany Kubik %A Sean Sather-Wagstaff %J Mathematics %D 2014 %I arXiv %X We introduce and study the weighted $r$-path ideal of a weighted graph $G_\omega$, which is a common generalization of Conca and De Negri's $r$-path ideal for unweighted graphs and Paulsen and Sather-Wagstaff's edge ideal of the weighted graph. Over a field, we explicitly describe primary decompositions of these ideals, and we characterize Cohen-Macaulayness of these ideals for trees (with arbitrary $r$) and complete graphs (for $r=2$). %U http://arxiv.org/abs/1408.1674v1
