In this PR, we study the behaviour of cochains (of the complex of homomorphisms) with respect to shifts on the source. In particular, we obtain an additive equivalence `leftShiftAddEquiv K L n a n' h : Cochain K L n ≃+ Cochain K⟦a⟧ L n'` when `h : n + a = n'`. Co-authored-by: Joël Riou <[email protected]>
