Abstract :
در اين مقاله، نا مساوي هايي براي شاخص CO-PI شامل تعدادي شاخص توپولوژيك، تعداد راس ها، تعداد يال ها و ماكسيمم درجه ارايه شده است. بعد از آن نتيجه اي براي درخت ها مي آوريم. علاوه بر اين موارد، نا مساوي هايي براي بزرگترين مقدار ويژه ماتريس CO-PI از گراف G به دست مي آوريم.
Abstract :
In this paper, we present some inequalities for the Co-PI index involving the
some topological indices, the number of vertices and edges, and the maximum degree. After
that, we give a result for trees. In addition, we give some inequalities for the largest
eigenvalue of the Co-PI matrix of G.
