This introductory graduate level text provides a relatively quick path to a special topic in
classical differential geometry: principal bundles. While the topic of principal bundles in
differential geometry has become classic even standard material in the modern graduate
mathematics curriculum the unique approach taken in this text presents the material in a way
that is intuitive for both students of mathematics and of physics. The goal of this book is to
present important modern geometric ideas in a form readily accessible to students and
researchers in both the physics and mathematics communities providing each with an
understanding and appreciation of the language and ideas of the other.
