About the book

Lectures on Symmetries provides an elementary introduction to the symmetries of plane figures and platonic solids keeping the prerequisite minimum. The symmetry of an object (in an Euclidean space) is measured in terms of its group of symmetries, which is a subgroup of the group of isometries of the Euclidean space. The primary focus of this book is on transformations of the plane, which helps in deeper understanding of geometry of plane objects. The approach used to understand various concepts is concrete and numerous diagrams are given for better explanation. This book also provides an elementary introduction to Group theory and Linear algebra. The book is a suitable text for an undergraduate course on Groups and Symmetries.

Key Features

  • All the basic notions of Matrix theory and Group theory are given The group of isometries of Euclidean Plane is described Isometries of Wall paper patterns are described with the help of various examples Rotational symmetries of all the five regular solids are described The solutions to all the problems are given at the end.
