We expand upon the notion of equivariant log concavity and make equivariant log concavity conjectures for Orlik–Solomon algebras of matroids, Cordovil algebras of oriented matroids, and Orlik–Terao algebras of hyperplane arrangements. In the case of the Coxeter arrangement for the Lie algebra |$\mathfrak{s}\mathfrak{l}_n$| , we exploit the theory of representation stability to give computer-assisted proofs of these conjectures in low degree.
