Signed graphs and inverses of their incidence matrices

Abdullah Alazemi, Milica Andelic, Sudipta Mallik

The Laplacian matrix $L$ of a signed graph $G$ may or may not be invertible. We present a combinatorial formula of the Moore-Penrose inverse of $L$ . This is achieved by finding a c…

The $μ$ -permanent, a new graph labeling, and a known integer sequence

Milica Anđelić, Carlos M. da Fonseca, António Pereira

Let $A = (a_{ij})$ be an $n$ -by- $n$ matrix. For any real number $μ$ , we define the polynomial $P_{μ} (A) = σ \in S_{n} \sum a_{1 σ (1)} \dots a_{nσ (n)} μ^{ℓ (σ)},$ as the $μ$ -permane…
