我们扩展了等变对数代数的概念,并对拟阵的Orlik-Solomon代数、定向拟阵的Cordovil代数和超平面排列的Orlik-Terao代数进行了等变对数代数的刻画。在李代数的Coxeter安排的情况下,我们利用表示稳定性理论给出了这些安排的计算机辅助证明。
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, we exploit the theory of representation stability to give computer-assisted proofs of these conjectures in low degree.
