David F. Anderson is Professor Emeritus of Mathematics at The University of Tennessee-Knoxville, a Fellow of the American Mathematical Society, and now lives in Murfreesboro, Tennessee. He received his BS degree from Iowa State University in 1971 and Ph D from the University of Chicago in 1976. His research interests are in commutative ring theory, particularly in divisibility and (non-unique) factorization in integral domains and associating graphs to commutative rings. He has written numerous research articles on these and related topics. T. Asir is the Assistant Professor and Head at Department of Mathematics-DDE, Madurai Kamaraj University, India. His research interests are in algebraic graph theory and combinatorial commutative algebra. He has published 23 research articles in Wo S-SCIE journals. His research work has been supported by various funding agencies like DST, UGC, SERB, CSIR and DSR-Saudi Arabia. He has delivered more than 50 invited talks at various conferences. Also, he has developed online mathematical content through MOOC Courses “Modern Algebra” and “Graph Theory” in SWAYAM-MHRD.
