Three Hopf algebras from number theory, physics & topology, and their common background II: general categorical formulation [PDF]
Communications in Number Theory and Physics, 2020 We consider three a priori totally different setups for Hopf algebras from number theory, mathematical physics and algebraic topology. These are the Hopf algebra of Goncharov for multiple zeta values, that of Connes-Kreimer for renormalization, and a Hopf algebra constructed by Baues to study double loop spaces.

Revealing topology in metals using experimental protocols inspired by K-theory
Nature Communications, 2023 Topological metals are conducting materials with gapless band structures and nontrivial edge-localized resonances. Their discovery has proven elusive because traditional topological classification methods require band gaps to define topological ...

Quarter-BPS states, multi-symmetric functions and set partitions
Journal of High Energy Physics, 2021 We give a construction of general holomorphic quarter BPS operators in N $$ \mathcal{N} $$ = 4 SYM at weak coupling with U(N) gauge group at finite N. The construction employs the Möbius inversion formula for set partitions, applied to multi-symmetric ...

Relative anomaly in (1+1)d rational conformal field theory
Physical Review Research, 2020 We study 't Hooft anomalies of symmetry-enriched rational conformal field theories (RCFT) in (1+1)d. Such anomalies determine whether a theory can be realized in a truly (1+1)d system with on-site symmetry, or on the edge of a (2+1)d symmetry-protected ...

Algebras with actions and automata
International Journal of Mathematics and Mathematical Sciences, 1982 In the present paper we want to give a common structure theory of left action, group operations, R-modules and automata of different types defined over various kinds of carrier objects: sets, graphs, presheaves, sheaves, topological spaces (in particular:

Topological cosets via anyon condensation and applications to gapped QCD2
Journal of High Energy PhysicsThe coset construction of two-dimensional conformal field theory (2D CFT) defines a 2D CFT by taking the quotient of two previously known chiral algebras.

On quasivarieties generated by (3-3)-snake lattices
Қарағанды университетінің хабаршысы. Математика сериясыThis paper addresses two classical and interrelated questions in universal algebra and lattice theory concerning the finite axiomatizability of quasivarieties and the standardness of topological quasivarieties generated by finite lattices.
