The acyclic matching number of a graph G is the largest size of an acyclic matching in G, that is, a matching M in G such that the subgraph of G induced by the vertices incident to edges in M is a forest. We show that the acyclic matching number of a connected subcubic graph G with m edges is at least m/6 except for two graphs of order 5 and 6. (C) 2018 Elsevier B.V. All rights reserved.
