Definition 12.25.2. Let $\mathcal{A}$ be an abelian category. Let $K^{\bullet , \bullet }$ be a double complex. We say the spectral sequence $({}'E_ r, {}'d_ r)_{r \geq 0}$ *weakly converges to $H^ n(\text{Tot}(K^{\bullet , \bullet }))$*, *abuts to $H^ n(\text{Tot}(K^{\bullet , \bullet }))$*, or *converges to $H^ n(\text{Tot}(K^{\bullet , \bullet }))$* if Definition 12.24.9 applies. Similarly we say the spectral sequence $({}''E_ r, {}''d_ r)_{r \geq 0}$ *weakly converges to $H^ n(\text{Tot}(K^{\bullet , \bullet }))$*, *abuts to $H^ n(\text{Tot}(K^{\bullet , \bullet }))$*, or *converges to $H^ n(\text{Tot}(K^{\bullet , \bullet }))$* if Definition 12.24.9 applies.
