Connected sum of graphs as molecular electronic devices
Irene Sciriha
Izvirni znanstveni članek
Oznake: molecular electronic device (MED);common eigenspace;μ–core vertices;connected–sum;
The connected sum Z of two root graphs of order n is obtained by gluing them together along a common subgraph G of order n − 1. The two vertices of Z not in G are called terminal vertices. The edged connected sum Z + e is obtained from Z by adding the edge joining the terminal vertices. We consider ...

Oznake: fibre-sum;eigenvalue perturbation;common eigenvector;μ-core vertices;vertex deletion;
The operation of fibre–sum, well known in topology as connected sum, joins two given manifolds together, along identical submanifolds. Analogously, the fibre–sum Z of two labelled connected root graphs H₁ and H₂ is obtained by gluing the two root graphs along a common subgraph G. For z₁ ∈ H₁ and z₂  ...
