Computer scientists are constantly searching for ways to squeeze ever more bandwidth from communications networks. Now a new approach to understanding a basic concept in graph theory, known as "vertex ...

Recent advances in the study of automorphism groups within graph theory have yielded significant theoretical and applied insights. At its core, the interplay between the algebraic structure of groups ...

Let 𝒟 be a non-trivial simple t-design. For 1 ≤ 𝑠 ≤ 𝑡, we generalize the concept of the incidence graph of 𝒟 and construct a new bipartite regular graph Γ. We obtain that the edge-transitivity of ...
