Graph theory is a branch of discrete mathematics that studies the relationship between objects that can be represented as vertices and edges of a graph. A graph consists of vertices or points connected by edges or lines, which represent the relationships or connections between these vertices. Graph theory has wide applications in various fields, including computer science, network engineering, chemistry, biology, economics, and so on. Rainbow antimagic coloring is one of the most interesting topics in graph theory which has attracted the attention of researchers all over the world in recent years. This concept involves coloring the nodes in the graph with different colors in such a way that each edge has a different weight and the total weight of each path from the initial node to the final node is different from one another. On 3 April and 10 April 2023, PUI-PT Combinatorics and Graph had the opportunity to hold an FGD (Focus Group Discussion) forum with Universiti Putra Malaysia (UPM). Prof. Drs. Dafik, M.Sc., Ph. D. as Chair of the PUI-PT Combinatorics and Graph opened this activity and welcomed several UPM students openly. Sharifah Kartini Said Husain, Ph.D. as a representative from UPM also received remarks from Prof. Dafik. Sharifah hopes that with this activity her students can get to know graph theory, especially rainbow antimagic coloring.
