I was applying equivaraint cohomology, in particular in the symplectic setting, for some time, but I feel like I am missing some nice books/course notes/articles. Could you advise me some literature, in particular where basic examples are worked out?
I think that the following notes are quite good, but I would like something more detailed and containing more examples/exercises: https://arxiv.org/abs/1112.1421Anderson - Introduction to equivariant cohomology in algebraic geometry.
