Using $k$-vertex amalgamations we obtain an {$\alpha$}-labeling of a graph that can be decomposed into multiple copies of a given {$\alpha$}-labeled graph as well as a robust family of irregular grids that can {$\alpha$}-labeled.
📌 3 Key Takeaways
🎯
Objective & Hypothesis:Graceful labelings constitute one of the classical subjects in the area of graph labelings; among them, the most restrictive type are those called {$\alpha$}-labelings.
📊
Key Findings & Data:In this work, we explore new techniques to generate {$\alpha$}-labeled graphs, such as vertex and edge duplications, replications of the entire graph, and $k$-vertex amalgamations.
💡
Conclusion & Impact:Using $k$-vertex amalgamations we obtain an {$\alpha$}-labeling of a graph that can be decomposed into multiple copies of a given {$\alpha$}-labeled graph as well as a robust family of irregular grids that can {$\alpha$}-labeled.
Graceful labelings constitute one of the classical subjects in the area of graph labelings; among them, the most restrictive type are those called {$\alpha$}-labelings. In this work, we explore new techniques to generate {$\alpha$}-labeled graphs, such as vertex and edge duplications, replications of the entire graph, and $k$-vertex amalgamations. We prove that for some families of graphs, it is possible to duplicate several vertices or edges. Using $k$-vertex amalgamations we obtain an {$\alpha$}-labeling of a graph that can be decomposed into multiple copies of a given {$\alpha$}-labeled graph as well as a robust family of irregular grids that can {$\alpha$}-labeled.
