Topological Indices With Degree Sequence $\mathcal{D}$ of Tree

In this paper, we refer to a asymptotic degree sequence as $\mathcal{D}=(d_1,d_2,\dots ,d_n)$. The examination of topological indices on trees gives us a general overview through bounds to find the maximum and minimum bounds which reflect the maximum and minimum number of edges incident to every vertex in the graph, Albertson index known as ${\sum }_{uv\in E(G)}\mid d_u(G)-d_v(G)\mid$, Sigma index $\sigma (G)$ among $\mathcal{D}$ of tree $T$ when $d_n⩾\cdots ⩾d_1$. According to the first zegrb we show for a degree sequence of order $n=4$, $\mathrm{irr}(T)=M_1(T{)}^2-2\sqrt{M_1(T)}+{\sum }_{i=1}^4\mid x_i-x_{i+1}\mid -(b+c)-1$.
