The -apex trees with minimum augmented Zagreb index
Muhuo Liu, Shumei Pang, Francesco Belardo +1
For a connected graph on at least three vertices, the augmented Zagreb index (AZI) of is defined as $$AZI(G)=\sum_{uv\in E(G)}\left(\frac{d(u)d(v)}{d(u)+d(v)-2}\right)^{3},…

Open problems in the spectral theory of signed graphs
Francesco Belardo, Sebastian M. Cioabă, Jack H. Koolen +1
Signed graphs are graphs whose edges get a sign or (the signature). Signed graphs can be studied by means of graph matrices extended to signed graphs in a natural way. Re…
