Introductory lectures on equivariant cohomology : (with appendices by Loring W. Tu and Alberto Arabia) /

"This book gives a clear introductory account of equivariant cohomology, a central topic in algebraic topology. Equivariant cohomology is concerned with the algebraic topology of spaces with a group action, or in other words, with symmetries of spaces. First defined in the 1950s, it has been in...
