题目:Specific elements and graphic structure of a ring

报告人:苏华东教授 (南宁师范大学)

Abstract : Associating a graph with a ring is an active research subject in algebraic graph theory, an area of mathematics in which methods of abstract algebra are employed in studying various graph invariants and tools in graph theory are used in studying various properties of a ring. Zero-divisors, nilpotent elements, idempotents and units are important elements of a ring. These elements are very useful for determining the properties of a ring. Based on these elements, one can define many graphs on a ring. Zero-divisor graph, unit graphs and unitary Cayley graphs are three popular graphs of a ring. In this talk, we mainly introduce the three graphs and give a brief summary about the three graphs.
