Research Abstract |
The existence of 2-factors of claw-free graphs can be determined by minimum degree condition without connectivity. In this research, by using Ryjacek closure, we replace problems on 2-factors in claw-free graphs with 2-factors of line graphs or the preimage graphs and analyzed structures of claw-free graphs.
