Direct sum graph of the subspaces of a finite dimensional vector space over finite fields

Bilal A. Wani, Aaqib Altaf, S. Pirzada +1

In this paper, we introduce a new graph structure, called the $d i r ec t s u m g r a p h$ on a finite dimensional vector space. We investigate the connectivity, diameter and the completen…

On the Estrada index of unicyclic and bicyclic signed graphs

Tahir Shamsher, S. Pirzada, Mushtaq A. Bhat

Let $Γ = (G, σ)$ be a signed graph of order $n$ with eigenvalues $μ_{1}, μ_{2}, \dots, μ_{n} .$ We define the Estrada index of a signed graph $Γ$ as $E E (Γ) = \sum_{i = 1}^{n} e^{μ_{i}}$ . We characteri…

Spectra of s-neighbourhood corona of two signed graphs

Tahir Shamsher, Mir Riyaz ul Rashid, S. Pirzada

A signed graph $S = (G, σ)$ is a pair in which $G$ is an underlying graph and $σ$ is a function from the edge set to ${\pm 1}$ . For signed graphs $S_{1}$ and $S_{2}$ on $n_{1}$ and…
