Stability of nontrivial graph pairs
Xiaomeng Wang, Xing Gao
A graph pair is called stable if every automorphism of the direct product is induced componentwise by automorphisms of and . A graph is twin-free if no t…

A Hopf algebra on subgraphs of a graph
Xiaomeng Wang, Shoujun Xu, Xing Gao
In this paper, we construct a bialgebraic and further a Hopf algebraic structure on top of subgraphs of a given graph. Further, we give the dual structure of this Hopf algebraic st…

Infinitesimal unitary Hopf algebras and planar rooted forests
Xing Gao, Xiaomeng Wang
Infinitesimal bialgebras were introduced by Joni and Rota. An infinitesimal bialgebra is at the same time an algebra and coalgebra, in such a way that the comultiplication is a der…
