Frucht Graph is not Hyperenergetic

If 1 2 , ,..., p    are the eigen values of a p-vertex graph , the energy of is G G 1 ( ) p i i E G     . If , then is said to be hyperenergetic. We show that the Frucht graph, the graph used in the proof of well known Frucht’s theorem, is not hyperenergetic. Thus showing that every abstract group is isomorphic to the automorphism group of some non-hyperenergetic graph. AMS Mathematics S...

A note on frucht diagrams, boolean graphs and hamilton cycles

Dejter, I.J., W. Cedefro and V. Jauregui, A note on Frucht diagrams, Boolean graphs and Hamilton cycles, Discrete Mathematics tL4 (1993) 131-135. We use tec.hniques based on F-diagrams to determine Hamilton cycles in some Boolean graphs. Let i,jeZ, with 0<i<j, andlet n:i-f j. Let RG;; be the graph induced by the middle levels of the Boolean algebra of the set {0, 1,..., n-l\. A generalization o...

The First ALS Ambulance in the World

The survival rate of medical emergencies depends highly on the intervention time and prompt medical care on the scene. The idea of “bring the doctor and medical equipment to the spot” was born in Hungary in the mid-1950s. The demand for advanced life support was a consequence of the fast growth of industry and traffic. It is worthwhile to review the development of the idea, the therapeutic meth...
