“…As explained in Remark 3.7, F is the column filtration on the total complex of a multicomplex (A, d 0 , d 1 , d 2 , d 3 ) with four differentials d i where, due to the shifts in the indices, d 0 = μ has bidegree (−1, 0), d 1 = ∂ has bidegree (0, 1), d 2 = ∂ has bidegree (1, 0) and d 3 = µ has bidegree (2, −1). The spectral sequence of a general multicomplex has been described by Livernet-Whitehouse-Ziegenhagen in [LWZ18] and gives the above equations in the case of a multicomplex with only four components.…”
