Opis

  Discovering Group Theory: A Transition to Advanced Mathematics presents the usual material that is found in a first course on groups and then does a bit more. The book is intended for students who find the kind of reasoning in abstract mathematics courses unfamiliar and need extra support in this transition to advanced mathematics. The book gives a number of examples of groups and subgroups, including permutation groups, dihedral groups, and groups of integer residue classes. The book goes on to study cosets and finishes with the first isomorphism theorem. Very little is assumed as background knowledge on the part of the reader. Some facility in algebraic manipulation is required, and a working knowledge of some of the properties of integers, such as knowing how to factorize integers into prime factors. The book aims to help students with the transition from concrete to abstract mathematical thinking.

O autorze

J. Benton Jones, Jr. , earned a BS degree in agricultural science from the University of Illinois and obtained MS and PhD degrees in agronomy from the Pennsylvania State University. He has written extensively on hydroponic topics and has been engaged in hydroponic research projects for much of his professional career. Dr. Jones is considered an authority on applied plant physiology and the use of analytical methods for assessing the nutrient element status of rooting media and plants as a means for ensuring plant nutrient element sufficiency in both soil and soilless crop production settings. At various times, he has served as a director of several university and commercial soil and plant analysis laboratories, and he still serves as an advisor for two such laboratories.
