Abstract

In this Research article we prove the following results:
1. The crown graph C_n⊙ K₁ is V₄-cordial for all n.
2. The armed crown AC_n is V₄-cordial for all n.
3. The pan graph C_n⁺¹ is V₄-cordial for all n.
4. The corona graph C_n⊙ mK₁ is V₄-cordial for all n and m.

Keywords: Klein-four group, V4-cordial labeling, crown, armed crown, pan graph.
