The algebra of primary cohomology operations computed by the well-known Steenrod algebra is one of the most powerful tools of algebraic topology. This book comp

The book develops the theory of secondary cohomology operations for singular cohomology theory. The author develops the subject in terms of elementary construct

Although the theory and applications of secondary cohomology operations are an important part of an advanced graduate-level algebraic topology course, there are

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
