Bridging Gaps In Elementary Mathematics

Chris,Amanfi  著
Ingram 出版
2022/11/22 出版

We cannot get away from Mathematics in our daily lives. It is omnipresent. Whatever the path we choose, we are likely to encounter Mathematics, in some form.This study supplement was created to improve upon the appreciation, and fundamental understanding of Mathematics, by employing the "WHY" of the Mathematics approach. It was also created to ensure that those who did not have an opportunity in their earlier years to study mathematics, or those who did but need better understanding, would be able to "BRIDGE" the gap formed in their education.The material covers topics found in the curriculum at the Primary to the pre-Junior High School level. It is not intended to substitute for formally prescribed schooling study materials and textbooks. Still, it is a supplement that provides a more profound understanding, real-life applications and different perspectives of the universal elements of the Mathematics curriculum. It effectively approaches the subject from the root to help make it less abstract.

Introduction to Quantum Groups

Teo,Banica  著
Springer 出版
2022/11/22 出版

This book introduces the reader to quantum groups, focusing on the simplest ones, namely the closed subgroups of the free unitary group.Although such quantum groups are quite easy to understand mathematically, interesting examples abound, including all classical Lie groups, their free versions, half-liberations, other intermediate liberations, anticommutation twists, the duals of finitely generated discrete groups, quantum permutation groups, quantum reflection groups, quantum symmetry groups of finite graphs, and more.The book is written in textbook style, with its contents roughly covering a one-year graduate course. Besides exercises, the author has included many remarks, comments and pieces of advice with the lone reader in mind. The prerequisites are basic algebra, analysis and probability, and a certain familiarity with complex analysis and measure theory. Organized in four parts, the book begins with the foundations of the theory, due to Woronowicz, comprising axioms, Haar measure, Peter-Weyl theory, Tannakian duality and basic Brauer theorems. The core of the book, its second and third parts, focus on the main examples, first in the continuous case, and then in the discrete case. The fourth and last part is an introduction to selected research topics, such as toral subgroups, homogeneous spaces and matrix models.Introduction to Quantum Groups offers a compelling introduction to quantum groups, from the simplest examples to research level topics.
