In this article, originally published online at DOI: 10.1080/14689361003769770 and in this issue pp. 351–358, the authors note that:
‘It was brought to our attention that Holmes (1980) discussed dynamics near a double homoclinic loop to a saddle-focus singularity in three dimensional differential equations in an earlier paper.
Regrettably we had not included his relevant paper in our references, and it is included below:
P.J. Holmes, A strange family of three-dimensional vector fields near a degenerate singularity. J. Diff. Eqs. 37(3) (1980), pp. 382–403.’
