This is a book in pure mathematics dealing with homotopy theory, one of the main branches of algebraic topology. The principal topics are as follows: Basic Homotopy; H-spaces and co-H-spaces; fibrations and cofibrations; exact sequences of homotopy sets, actions, and coactions; homotopy pushouts and pullbacks; classical theorems, including those of Serre, Hurewicz, Blakers-Massey, and Whitehead; homotopy Sets; homotopy and homology decompositions of spaces and maps; and obstruction theory. The underlying theme of the entire book is the Eckmann-Hilton duality theory. The book can be used as a text for the second semester of an advanced ungraduate or graduate algebraic topology course.

Carefully written treatment of a basic subject by a research worker in the field Provides motivation with many illustrations and exercises Exposition moves at a moderate pace, even in the later chapters Differs from other texts on homotopy theory, in that the unifying theme of the entire book is the Eckmann-Hilton duality theory Several appendices provide background information Includes supplementary material: sn.pub/extras
