Abstract

The forgotten topological index of G is specified the degrees 𝑑𝑖 and 𝑑𝑗
. In this paper, we find some bounds for the eigenvalues of
forgotten topological matrix and we establish some inequalities about forgotten Estrada topological index.

Abstract

G’ nin unutulmuş topolojiksel indeksi 𝑑𝑖 ve 𝑑𝑗 dereceleriyle tanımlanır. Bu makalede, unutulmuş topolojiksel indeksin özdeğerleri
için bazı sınırlar bulunmuştur ve unutulmuş Estrada topolojiksel indeks ile ilgili bazı eşitsizlikler belirlenmiştir.
