## Homology of coloured posets: A generalisation of Khovanov's cube construction

### In: Journal of Algebra, 2009, vol. 322, no. 2, p. 429-448

We define a homology theory for a certain class of posets equipped with a pre-sheaf of modules. We show that when restricted to Boolean lattices this homology is isomorphic to the homology of the “cube” complex defined by Khovanov. Plus

Summary
We define a homology theory for a certain class of posets equipped with a pre-sheaf of modules. We show that when restricted to Boolean lattices this homology is isomorphic to the homology of the “cube” complex defined by Khovanov.
