Idea

In homological algebra it turns out that a host of common (co)homological constructions (such as group homology, cyclic homology, etc.) may be cast in a unified way as homotopy limits of functors on categories of presentations of the given algebraic structure (group, Lie algebra, associative algebra, etc.) [Ivanov & Mikhailov 2015], in fact all these functors may systematically be indexed by “fr-codes” [Ivanov & Mikhailov 2017].
