Anahtar Kelimeler:The first Zagreb index, , The second Zagreb index
Özet: Let $G = (V, E)$ be a graph. The first Zagreb index and second Zagreb index of $G$ are defined as $\sum_{v \in V}d^2(v)$ and $\sum_{uv \in E}d(u)d(v)$, respectively. Using first and second Zagreb indexes of graphs, we in this note present sufficient conditions for some Hamiltonian properties of graphs. Let $G = (V, E)$ be a graph.
