In this talk we give a purely derivator-theoretic reformulation and proof of a classic result of Happel and Ladkani, showing that it occurs uniformly across stable derivators and it is then independent of coefficients. The resulting equivalence provides a bridge between homotopy theory and representation theory: indeed, we explain how our result is a derivator-theoretic version of the ∞-Dold-Kan correspondence for bounded chain complexes.
