Large $$N_\mathrm{f}$$ N f for multiple representations
European Physical Journal C: Particles and Fields, 2021 We present an extension of the large- $$N_\mathrm{f}$$ N f formalism that allows one to study cases with multiple fermion representations. The pole structure in the beta function is traced back to the intrinsic non-abelian nature of the gauge group ...

Higher Extensions of Abelian Varieties [PDF]
Nagoya Mathematical Journal, 1968 In this paper we prove:THEOREM: Let k be an algebraically closed field of characteristic p > 0, and let X and Y be abelian varieties over k. Then the group Ext2(X, Y) = 0.

Anomalies of non-Abelian finite groups via cobordism
Journal of High Energy Physics, 2022 We use cobordism theory to analyse anomalies of finite non-abelian symmetries in 4 spacetime dimensions. By applying the method of ‘anomaly interplay’, which uses functoriality of cobordism and naturality of the η-invariant to relate anomalies in a group

Genera in abelian extensions [PDF]
Proceedings of the American Mathematical Society, 1975 The principal genus in an abelian extension is characterized as the kernel of norm residue symbols at the ramified primes.

Deformations and Extensions of Modified λ-Differential 3-Lie Algebras
Mathematics, 2023 In this paper, we propose the representation and cohomology of modified λ-differential 3-Lie algebras. As their applications, the linear deformations, abelian extensions and T∗-extensions of modified λ-differential 3-Lie algebras are also studied.

Wintenberger’s functor for abelian extensions [PDF]
Journal de théorie des nombres de Bordeaux, 2010 Let k be a finite field. Wintenberger used the field of norms to give an equivalence between a category whose objects are totally ramified abelian p -adic Lie ...

Inverse property of nonassociative abelian extensions [PDF]
Commentationes Mathematicae Universitatis Carolinae, 2021 Our paper deals with the investigation of extensions of commutative groups by loops so that the quasigroups that result in the multiplication between cosets of the kernel subgroup are T-quasigroups. We limit our study to extensions in which the quasigroups determining the multiplication are linear functions without constant term, called linear abelian ...

Field redefinition's help in constructing non-abelian gauge theories
Physics Letters B, 2019 We study, using the example of general covariance, to what extent a would-be non-abelian extension of free field abelian gauge theory can be helped by a field redefinition; answer – not much!

Lattice BF theory, dumbbells, and composite fermions
Nuclear Physics B, 2022 We formulate U(1) bda Chern-Simons theory, which is also called BF theory, on a lattice, adapting a method proposed by Kantor and Susskind [1] for the groups R and ZN. Our method applies to any finite or infinite abelian group.

The holographic non-abelian vortex
Journal of High Energy Physics, 2019 We study a fully back-reacted non-abelian vortex solution in an extension of the holographic superconductor setup. The thermodynamic properties of the vortex are computed.
