Cohomology operations and applications in homotopy theory

Robert E. Mosher, Martin C. Tangora0486466647, 9780486466644

Cohomology operations are at the center of a major area of activity in algebraic topology. This treatment explores the single most important variety of operations, the Steenrod squares. It constructs these operations, proves their major properties, and provides numerous applications, including several different techniques of homotopy theory useful for computation. 1968 edition.
