Abstract

We prove that for any positive integers kk and dd, if a graph GG has maximum average degree at most 2k+2dd+k+12k + \frac{2d}{d+k+1}, then GG decomposes into k+1k+1 pseudoforests C1,,Ck+1C_{1},\ldots,C_{k+1} such that there is an ii such that for every connected component CC of CiC_{i}, we have that e(C)de(C) \leq d.
