Frequency control of singularly perturbed forced Duffing's oscillator
Robert Vrabel, Marcel Abas
We analyze the dynamics of the forced singularly perturbed differential equation of Duffing's type. We explain the appearance of the large frequency nonlinear oscillations of the s…
Large Cayley digraphs and bipartite Cayley digraphs of odd diameters
Marcel Abas, Tomas Vetrik
Let be the largest number of vertices in a Cayley digraph of degree and diameter , and let be the largest order of a bipartite Cayley digraph for given…
Cayley graphs of diameter two with order greater than 0.684 of the Moore bound for any degree
Marcel Abas
It is known that the number of vertices of a graph of diameter two cannot exceed . In this contribution we give a new lower bound for orders of Cayley graphs of diameter two…
Large Networks of Diameter Two Based on Cayley Graphs
Marcel Abas
In this contribution we present a construction of large networks of diameter two and of order for every degree , based on Cayley graphs with surprisingly…
