A method to determine algebraically integral Cayley digraphs on finite Abelian group
Fei Li
Researchers in the past have studied eigenvalues of Cayley digraphs or graphs. We are interested in characterizing Cayley digraphs on a finite Abelian group G whose eigenvalues are…
Circulant Digraphs Integral over Number Fields
Fei Li
A number field K is a finite extension of rational number field Q. A circulant digraph integral over K means that all its eigenvalues are algebraic integers of K. In this paper we…
Lattice-ordered matrix algebras over real GCD-domains
Fei Li, Xianlong Bai, Derong Qiu
Let be a GCD-domain. In this paper, Weinberg's conjecture on the matrix algebra is proved. Moreover, all the lattice order…
A graphical method to calculate Selmer groups of several families of non-CM elliptic curves
Fei Li, Derong Qiu
In this paper, we extend the ideas of Feng [F1], Feng-Xiong [FX] and Faulkner-James [FJ] to calculate the Selmer groups of elliptic curves $ y^{2} = x (x + \varepsilon p D) (x + εq…
On several families of elliptic curves with arbitrary large Selmer groups
Fei Li, Derong Qiu
In this paper, we calculate the Selmer groups $ S^{(ϕ)} (E / \Q) $ and $ S^{(\hatφ)} (E^{\prime} / \Q) $ of elliptic curves via desc…
