Название: COHOMOLOGY OPERATIONS AND APPLICATIONS IN HOMOTOPY THEORY
Авторы: ROBERT E. MOSHER, MARTIN С. TANGORA
In the past two decades, cohomology operations have been the center of a major area of activity in algebraic topology. This technique for supplementing and enriching the algebraic structure of the cohomology ring led to important progress, both in general homotopy theory and i η specific geometric applications. For both theoretical and practical reasons, much analysis has been made of the formal properties of families of operations.
