K Theory and Characteristic Classes: A Homotopical Perspective

This book offers a modern introduction to characteristic classes and topological K-theory, two foundational topics in algebraic topology. It incorporates contemporary tools such as category theory, spectra, and modern homotopy theory, making the material more accessible and relevant for today’s graduate students. It is intended as an "on-ramp" to advanced study, emphasizing practical application over exhaustive theoretical background. The book is not designed to be self-contained. It introduces essential tools from modern homotopy theory without delving deeply into their foundations, focusing instead on how these tools are used in practice. It occasionally cites results without proof, directing readers to external sources. This approach encourages students to develop research habits, such as consulting references and exploring topics independently.
