Edge chromatic index and edge-sum chromatic index for families of integral sum graphs

Priyanka B R, Biswajit Pandit, Rajeswari M

We consider class of integral sum graphs $H_{m,j}^{-i,s}$ subject to the conditions $-i<0<s$, $1\le m<i$ and $1\le j<s$ for all $i,s,m,j\in \mathbb{N}$. We apply edge-sum co…
