Oct 22, 2013 at 0:31 comment added user40096 Hello,Tony Huynh,I want to proof the simplest case:$C$ is $2n$-cycle and there are $n$ ears on $C$ in all such that (as you said)every ear is a $C$-path with two edges and every two ears do not have common vertex.So every vertex of $C$ is a end of an ear.But I can not proof it or give a counterexample.
