The largest normalized Laplacian eigenvalue and incidence balancedness of simplicial complexes

Yi-min Song, Hui-Feng Wu, Yi-Zheng Fan

Let $K$ be a simplicial complex, and let $I^_{i}^{u p} (K)$ be the $i$ -th up normalized Laplacian of $K$ . Horak and Jost showed that the largest eigenvalue of $I^_{i}^{u p} (K)$ is at most…

The largest Laplacian eigenvalue and the balancedness of simplicial complexes

Yi-Zheng Fan, Hui-Feng Wu, Yi Wang

Let $K$ be a simplical complex, and let $L_{i}^{u p} (K), Q_{i}^{u p} (K)$ be the $i$ -th up Laplacian and signless Laplacian of $K$ , respectively. In this paper we prov…
