<br/><br/>  This text systematically presents the basics of quantum mechanics, e mphasizing the role of Lie groups, Lie algebras, and their unitary repr esentations. The mathematical structure of the subject is brought to th e fore, intentionally avoiding significant overlap with material from s tandard physics courses in quantum mechanics and quantum field theory. The level of presentation is attractive to mathematics students looking to learn about both quantum mechanics and representation theory, while also appealing to physics students who would like to know more about t he mathematics underlying the subject. This text showcases the numerous differences between typical mathematical and physical treatments of th e subject. The latter portions of the book focus on central mathematica l objects that occur in the Standard Model of particle physics, underli ning the deep and intimate connections between mathematics and the phys ical world. While an elementary physics course of some kind would be he lpful to the reader, no specific background in physics is assumed, maki ng this book accessible to students with a grounding in multivariable c alculus and linear algebra. Many exercises are provided to develop the reader's understanding of and facility in quantum-theoretical concepts and calculations.
