Specifically, we prove that the mod $p$ homology growth equals the dimension of the group homology with coefficients in a certain universal division ring and this is independent of the choice of residual chain. We also consider a number of applications to fibring, amenable category, and minimal volume entropy.", "revisions": [ { "version": "v1", "updated": "2022-12-06T18:02:43.000Z" } ], "analyses": { "subjects": [ "20J05", "16K99", "16S35", "20E26", "20F36", "20F65", "57M07" ], "keywords": [ "positive characteristic", "artin kernels", "homological growth", "finite rationally soluble groups", "minimal volume entropy" ], "note": { "typesetting": "TeX", "pages": 21, "language": "en", "license": "arXiv", "status": "editable" } } }
