# Matrix Groups for Undergraduates

Share this page
*Kristopher Tapp*

Matrix groups are a beautiful subject and are central to many fields in
mathematics and physics. They touch upon an enormous spectrum within the
mathematical arena. This textbook brings them into the undergraduate
curriculum. It is excellent for a one-semester course for students familiar
with linear and abstract algebra and prepares them for a graduate course on Lie
groups.

Matrix Groups for Undergraduates is concrete and example-driven, with
geometric motivation and rigorous proofs. The story begins and ends with the
rotations of a globe. In between, the author combines rigor and intuition to
describe basic objects of Lie theory: Lie algebras, matrix exponentiation, Lie
brackets, and maximal tori. The volume is suitable for graduate students and
researchers interested in group theory.

#### Readership

Undergraduates and beginning graduate students interested in group theory.

#### Reviews

this is an excellent, well-written textbook which is strongly recommended to a wide audience of readers interested in mathematics and its applications. The book is suitable for a one-semester undergraduate lecture course in matrix groups, and would also be useful supplementary reading for more general group theory courses.
