Today, I am writing about Leray spectral sequence and Serre–Hochschild spectral sequence. Those are important spectral sequences in arithmetic geometry and number theory, in particular, I care about their uses in the study of Galois cohomology and other cohomology theories. I will use the text of ⟦cite:NSW08⟧ .
