Formal higher-spin theories and Kontsevich–Shoikhet–Tsygan formality
Nuclear Physics B, 2017 The formal algebraic structures that govern higher-spin theories within the unfolded approach turn out to be related to an extension of the Kontsevich formality, namely, the Shoikhet–Tsygan formality.

, 1983 Quantum Markov Chains were defined by the first author [Non-commutative Markov chains. Proc. School Math. Phys. Camarino, 268-295 (1974)] as states \(\phi\) on the infinite \(C^*\)-tensor product A of countably many copies of a matrix algebra M, possessing an intrinsic statistical property (formulated in terms of generalized conditional expectations ...

Forum of Mathematics, SigmaGiven a continuous linear cocycle $\mathcal {A}$ over a homeomorphism f of a compact metric space X, we investigate its set $\mathcal {R}$ of Lyapunov-Perron regular points, that is, the collection of trajectories of f that obey the ...

Umbilic Lines in Orientational Order
Physical Review X, 2016 Three-dimensional orientational order in systems whose ground states possess nonzero gradients typically exhibits linelike structures or defects: λ lines in cholesterics or Skyrmion tubes in ferromagnets, for example. Here, we show that such lines can be

On two-dimensional tensor network group symmetries
New Journal of PhysicsWe introduce two-dimensional tensor-network representations of finite groups carrying a 4-cocycle index. We characterize the associated gapped (2+1)D phases that emerge when these anomalous symmetries act on tensor-network ground states.

Translation Invariant Spaces and Asymptotic Properties of Variational Equations
Abstract and Applied Analysis, 2011 We present a new perspective concerning the study of the asymptotic behavior of variational equations by employing function spaces techniques. We give a complete description of the dichotomous behaviors of the most general case of skew-product flows ...

CFTs with large gap from Barnes-Wall lattice orbifolds
Journal of High Energy PhysicsWe investigate orbifolds of lattice conformal field theories with the goal of constructing theories with large gap. We consider Barnes-Wall lattices, which are a family of lattices with no short vectors, and orbifold by an extraspecial 2-group of lattice

پژوهشهای ریاضی, 2021 Introduction Representation as well as central extension are two of the most important concepts in the theory of Lie (super)algebras. Apart from the interest of mathematicians, the attention of physicist are also drawn to these two subjects because of ...

Klasifikasi Aljabar Lie Forbenius-Quasi Dari Aljabar Lie Filiform Berdimensi ≤ 5
Jambura Journal of MathematicsIn this research, we studied quasi-Frobenius Lie algebras and filiform Lie algebras of dimensions ≤ 5 over real field. The primary objective of this research is to classify the classification of filiform Lie algebras of dimensions ≤ 5 into quasi ...

Cocycles, Symplectic Structures and Intersection
Geometric And Functional Analysis, 1999 We investigate the cross ratio for closed negatively curved manifolds. As one of several applications, we obtain that for two such homotopy equivalent manifolds M and N, the following is true : If M and N have the same marked length spectrum and if the Anosov splitting for M is C^1 then M and N have the same volume.
