Quasicrystalline Chern Insulators

Ai-Lei He, Lu-Rong Ding, Yuan Zhou +2

Chern insulator or quantum anomalous Hall state is a topological state with integer Hall conductivity but in absence of Landau level. It had been well established on various two-di…

Partially normal 5-edge-colorings of cubic graphs

Ligang Jin, Yingli Kang

In a proper edge-coloring of a cubic graph, an edge is normal if the set of colors used by the edges adjacent to has cardinality 3 or 5. The Petersen coloring conjecture as…

A general q-expansion formula based on matrix inversions and its applications

Jin Wang

In this paper, by use of matrix inversions, we establish a general -expansion formula of arbitrary formal power series with respect to the base $$\left\{z^n\frac{(az:q)_n…
