Majority coset decoding

, 1993
A majority coset decoding (MCD) procedure that can be applied to an arbitrary geometric code is discussed. In general, the basic algorithm for decoding of algebraic-geometric codes does not correct up to the designed minimum distance. In MCD, a reduction

Algebras in tensor categories and coset conformal field theories

, 2004
The coset construction is the most important tool to construct rational conformal field theories with known chiral data. For some cosets at small level, so-called maverick cosets, the familiar analysis using selection and identification rules breaks down.

Fermionic coset models as topological models [PDF]

, 2021
By considering the fermionic realization of G/H coset models, we show that the partition function for the U(1)/U(1) model defines a topological quantum field theory and coincides with that of a two-dimensional Abelian BF system.

Symmetries, universes and phases of QCD2 with an adjoint Dirac fermion

Journal of High Energy Physics
We study 2d SU(N) QCD with an adjoint Dirac fermion. Assuming that the IR limit of the massless theory is captured by a WZW coset CFT, we show that this CFT can be decomposed into a sum of distinct CFTs, each representing a superselection sector ...

Model Building by Coset Space Dimensional Reduction Scheme Using Twelve-Dimensional Coset Spaces [PDF]

, 2023
We investigate the twelve-dimensional gauge-Higgs unification models with an eight-dimensional coset space. For each model, we apply the coset space dimensional reduction procedure and examine the particle contents of the resulting four-dimensional ...

Efficient arithmetic regularity and removal lemmas for induced bipartite patterns

Discrete Analysis, 2019
Efficient arithmetic regularity and removal lemmas for induced bipartite patterns, Discrete Analysis 2019:3, 14 pp. This paper provides a common extension of two recent lines of work: the study of arithmetic regularity lemmas under the model-theoretic ...

Notes on retracts of coset spaces

, 2005
We study retracts of coset spaces. We prove that in certain spaces the set of points that are contained in a component of dimension less than or equal to n, is a closed set.

D-branes in coset models [PDF]

, 2001
The analysis of D-branes in coset models G/H provides a natural extension of recent studies on branes in WZW-theory and it has various interesting applications to physically relevant models.

New Perspectives on Kac–Moody Algebras Associated with Higher-Dimensional Manifolds

Axioms
In this review, we present a general framework for the construction of Kac–Moody (KM) algebras associated to higher-dimensional manifolds. Starting from the classical case of loop algebras on a circle S1, we extend the approach to compact and non-compact
