Cohomology operations are at the center of a major area of activity in algebraic topology. This treatment explores the single most important variety of operatio
As the title suggests, this book is concerned with the elementary portion of the subject of homotopy theory. It is assumed that the reader is familiar with the
This book is the result of a conference held to examine developments in homotopy theory in honor of Samuel Gitler in July 1993 (Cocoyoc, Mexico). It includes se
The most important invariant of a topological space is its fundamental group. When this is trivial, the resulting homotopy theory is well researched and familia
