Orders On Free Metabelian Groups
Wenhao Wang
A bi-order on a group is a total, bi-multiplication invariant order. A subset in an ordered group is convex if for all in , every element…
Subgroup Distortion and the Relative Dehn Functions of Metabelian Groups
Wenhao Wang
We show the connection between the relative Dehn function of a finitely generated metabelian group and the distortion function of a corresponding subgroup in the wreath product of…
Dehn Function of Finitely Presented Metabelian Groups
Wenhao Wang
In this paper, we compute an upper bound for the Dehn function of a finitely presented metabelian group. In addition, we prove that the same upper bound works for the relative Dehn…
Chimera dynamics in nonlocally coupled moving phase oscillators
Wenhao Wang, Qionglin Dai, Hongyan Cheng +2
Chimera states, a symmetry-breaking spatiotemporal pattern in nonlocally coupled dynamical units, prevail in a variety of systems. However, the interaction structures among oscilla…
