I am trying to understand some part of J. Greenlees's "Four approaches to cohomology theories with reality": https://arxiv.org/abs/1705.09365
I have a problem with understanding $RO(Q)$-graded homotopy fixed point spectral sequence. Namely: 1. In section 2.C, proof of Lemma 2.1 - how filtration on $EQ_+$ helps us in describing $E_1$-page of this spectral sequence? And why it looks as described?
Which leads to seceond question:
- How this spectral sequence arises?
Any help or reference would be strongly appreciated.
