%0 Journal Article %T A formula for the energy of circulant graphs with two generators %A Justine Louis %J Mathematics %D 2015 %I arXiv %X In this note, we derive closed formulas for the energy of circulant graphs generated by $1$ and $\gamma$, where $\gamma\geqslant2$ is an integer. We also find a formula for the energy of the complete graph without a Hamilton cycle. %U http://arxiv.org/abs/1508.02348v1
