The Grand Rapids Community College Mathematics Department is pleased to announce that it will host its first Mathematics Seminar of the 2015-2016 academic year on Wednesday, September 23, 3:00 – 4:00 PM in 102 Cook. Our speaker, Sang Lee, will discuss topics from graph theory. The title and abstract of his talk are below.
Sang’s talk will focus on the concepts and applications of graph labeling. A working knowledge of arithmetic and a desire to learn more about mathematics are the only things needed to appreciate the ideas to be presented, so, as always, everyone is welcome to attend!
Pop and cookies will be served at 2:45 PM.
The concepts of graph labeling began about 50 years ago, and have been research topics for many mathematicians all over the world. While there are many different graph labeling techniques, in this seminar talk we will focus mainly on the three most popular graph labelings: a vertex labeling called graceful labeling, and edge labelings called magic and super-magic labeling. We will also investigate how these graph labelings are applied to graph decompositions and well-known magic squares.
