Evolution of weights on a connected finite graph
Jicheng Ma, Yunyan Yang
On a connected finite graph, we propose an evolution of weights including Ollivier's Ricci flow as a special case. During the evolution process, on each edge, the speed of change o…
A modified Ricci flow on arbitrary weighted graph
Jicheng Ma, Yunyan Yang
In this paper, we propose a modified Ricci flow, as well as a quasi-normalized Ricci flow, on arbitrary weighted graph. Each of these two flows has a unique global solution. In par…
On automorphism groups of polar codes
Jicheng Ma, Guiying Yan
Over the past years, Polar codes have arisen as a highly effective class of linear codes, equipped with a decoding algorithm of low computational complexity. This family of codes s…
On automorphism groups of binary cyclic codes
Ma Jicheng, Yan Guiying
A lot of attention has been paid to the investigation of the algebraic properties of linear codes. In most cases, this investigation involves the determination of required code aut…
