Higher nerves of simplicial complexes
Algebraic Combinatorics, Volume 2 (2019) no. 5, pp. 803-813.

We investigate generalized notions of the nerve complex for the facets of a simplicial complex. We show that the homologies of these higher nerve complexes determine the depth of the Stanley-Reisner ring k[Δ] as well as the f-vector and h-vector of Δ. We present, as an application, a formula for computing regularity of monomial ideals.
