Asymmetric Fermi superfluid with different atomic species in a harmonic trap

C. -H. Pao, shin-Tza Wu, S. -K. Yip

We study the dilute fermion gas with pairing between two species and unequal concentrations in a harmonic trap using the mean field theory and the local density approximation. We f…

Coloring of graphs associated to zero-divisors

Hsin-Ju Wang

Let $G$ be a graph, $χ (G)$ be the minimal number of colors which can be assigned to the vertices of $G$ in such a way that every two adjacent vertices have different colors and $ω(…

Removable singularity of the polyharmonic equation

Shu-Yu Hsu

Let $x_{0} \in Ω \subset R^{n}$ , $n \geq 2$ , be a domain and let $m \geq 2$ . We will prove that a solution $u$ of the polyharmonic equation $Δ^{m} u = 0$ in $Ω ∖ {x_{0}}$ has a removabl…

Commutative rings with toroidal zero-divisor graphs

Hung-Jen Chiang-Hsieh, Neal O. Smith, Hsin-Ju Wang

Let $R$ be a commutative ring and $Γ (R)$ denote its zero-divisor graph. In this paper, we investigate the genus number of the compact Riemann surface which $Γ (R)$ can be embedded a…
