Minimal groups of given representation dimension
Jonathan Cohen
For a finite group , let denote the smallest dimension of a faithful, complex linear representation of . It is clear that …
Finite Groups With Two Irredundant Covers
Jonathan Cohen, Kyle Rosengartner
An irredundant cover of a finite group is a collection of proper subgroups whose union is and which contains no smaller subcover. We classify finite groups which possess ex…
Coherence for rewriting 2-theories
Jonathan Asher Cohen
General coherence theorems are constructed that yield explicit presentations of categorical and algebraic objects. The categorical structures involved are finitary discrete Lawvere…
Coherent presentations of structure monoids and the Higman-Thompson groups
Jonathan A. Cohen
Structure monoids and groups are algebraic invariants of equational varieties. We show how to construct presentations of these objects from coherent categorifications of equational…
Coherence without unique normal forms
Jonathan A. Cohen
Coherence theorems for covariant structures carried by a category have traditionally relied on the underlying term rewriting system of the structure being terminating and confluent…
Restricted exchange, braidings and the monoidal centre
Jonathan A. Cohen, Craig A. Pastro
Braided monoidal categories arise naturally as centres of monoidal categories and have been the focus of much recent attention in both mathematics and physics. By suitably restrict…
