The construction of braided $T$ -category via Yetter-Drinfeld-Long bimodules

Daowei Lu, Yan Ning, Dingguo Wang

Let $H_{1}$ and $H_{2}$ be Hopf algebras which are not necessarily finite dimensional and $α, β \in A u t_{H o p f} (H_{1}), γ, δ \in A u t_{H o p f} (H_{2})$ . In this paper, we introduce a category ${}_{…

Analytic properties of sextet polynomials of hexagonal systems

Guanru Li, Lily Li Liu, Yi Wang

In this paper we investigate analytic properties of sextet polynomials of hexagonal systems. For the pyrene chains, we show that zeros of the sextet polynomials $P_{n} (x)$ are real,…

Strong coupling superconductivity in trilayer film LiB $_{2}$ C $_{2}$

Miao Gao, Xun-Wang Yan, Zhong-Yi Lu +1

Coupling between $σ$ -bonding electrons and phonons is generally very strong. To metallize $σ$ -electrons provides a promising route to hunt for new high-T $_{c}$ superconductors. Based…

Observation of the decays $χ_{c J} \to ϕϕ η$

BESIII Collaboration, M. Ablikim, M. N. Achasov +481

Using a data sample of $(448.1 \pm 2.9) \times 1 0^{6}$ $ψ (3686)$ decays collected by the BESIII detector at the Beijing Electron Positron Collider (BEPCII), we observe the decays $χ_{c…

Weierstrass Semigroups From a Tower of Function Fields Attaining the Drinfeld-Vladut Bound

Shudi Yang, Chuangqiang Hu

For applications in algebraic geometric codes, an explicit description of bases of Riemann-Roch spaces of divisors on function fields over finite fields is needed. We investigate t…

Coefficients of (inverse) unitary cyclotomic polynomials

G. Jones, P. I. Kester, L. Martirosyan +4

The notion of block divisibility naturally leads one to introduce unitary cyclotomic polynomials $Φ_{n}^{*} (x)$ . They can be written as certain products of cyclotomic poynomials. We st…
