On semi-odd linear partitions of cubic graphs

A linear forest is a graph in which each connected component is a chordless path. A linear partition of a graph $ G$ is a partition of its edge set into linear forests and $ la(G)$ is the minimum number of linear forests in a linear partition. For a cubic graph $ G$ it is known that $ la(G)=2$. A linear partition $ L = (L_1, L_2)$ is said to be semi-odd whenever each component of $ L_1$ (or each component of $ L_2$) has odd length. We study relationschips between semi-odd linear partitions and perfect matchings.
