## Abstract Kotzig asked in 1979 what are necessary and sufficient conditions for a __d__βregular simple graph to admit a decomposition into paths of length __d__ for odd __d__>3. For cubic graphs, the existence of a 1βfactor is both necessary and sufficient. Even more, each 1βfactor is extendable

β¦ Synopsis
The k-linear arboricity of a graph G is the minimum number of forests whose connected components are paths of length at most k which partition E(G). Motivated by this index, we investigate a variation of this idea for d-regular graphs. Namely, we define a d-regular graph G to be (l,k)-linear arborific if E(G) can be partitioned into edge sets of l linear forests consisting of paths of length at most k. By extending an inductive tool developed by Jackson and Worrnald, we determine, for d/>4, values of k such that every d-regular graph is (d -1, k)-linear arborific. (~

## Abstract A regular multigraph with maximum multiplicity __r__ and degree __rs__ cannot always be factored into __r s__βregular simple graphs. It is shown, however, that under general conditions a similar factorization can be achieved if we first allow the addition or deletion of a relatively sma
