The energy of a graph $G$ is the sum absolute values eigenvalues adjacency matrix $G$. Let $s^+(G), s^-(G)$ denote squares positive and negative $G$, respectively. It was conjectured by [Elphick, Farber, Goldberg, Wocjan, Discrete Math. (2016)] that if connected order $n$, then $s^+(G)\geq n-1$ $s^-(G) \geq n-1$. In this paper, we show partial results towards conjecture. particular, numerous st...

Homo Reciprocans: Survey Evidence on Behavioural Outcomes This paper complements the experimental literature that has shown the importance of reciprocity for behaviour in stylized labour markets or other decision settings. We use individual measures of reciprocal inclinations in a large, representative survey, and relate reciprocity to real world labour market behaviour and life outcomes. We fi...
